To be honest i don't understand the problem. The method with the PID file (or, to show that i can use the terminology like any real computer scientist - semaphore) is a standard method of interprocess communication:
This should work without under any circumstance, regardless of wether the system is fast or not.

FVWM-THEMES-COM(1) Fvwm Utility FVWM-THEMES-COM(1)NAME
fvwm-themes-com - fvwm-themes communication center
SYNOPSIS
fvwm-themes-com [ --help] [ --version] [ --name name ] [ --message message ] [ --lock-and-get ] [ --get-buffer ] [ --clear-buffer ] [
--buffer-name name ] [ --line lineNbr]
DESCRIPTION
This script is not a user script. It is used by Fvwm-Themes for communication between some FvwmScript scripts and some other programs.
Basically, you want to start a programs in the background which support the fvwm-themes-com communication protocol (e.g., fvwm-themes-menu-
app and fvwm-themes-config with the com-mode option can be used as generic examples), then you can use fvwm-themes-com to ask questions or
to give instructions to the background program. The answer are displayed by fvwm-themes-com in the standard out put and can be used by a
FvwmScript script via the GetoutPut instruction. The advantage of using this method is that the background program have to do its main job
only once (e.g., parsing a lot of informations and storing them in some variables) and a script can have very fast answer from the back-
ground program via fvwm-themes-com.
OPTIONS --help - show the help and exit
--version - show the version and exit
--name name - the name of the communication (e.g., if you start fvwm-themes-menuapp with --com-name pid option you must use menuapp-pid as
name to communicate with it). The pipe used for communication are $FVWM_DATADIR/{.tmp-com-in-name,tmp-com-out-name,tmp-com-lock-name}. The
"buffer" file is $FVWM_USERDIR/.tmp-com-buffer-name
--message - A one line message to be sent to the back program.
--lock-and-get - Wait (a certain "time out") for an answer of the message. Then, the answer is displayed on STDOUT.
--line n - n must be an integer n > 0. In the case of a lock and get message, fvwm-themes-com will out put only the nth line of the answer
of the back program on STDOUT and will copy the complete answer in a "buffer" file. If you use the get-buffer option the nth line of the
buffer is out put on STDOUT.
--get-buffer - Out put the buffer file on STDOUT.
--buffer-name othername - Use an alternative name for the buffer file: $FVWM_USERDIR/.tmp-com-buffer-othername. This is usefull if two pro-
grams use the same background program and both use the buffer.
--clear-buffer - remove the buffer file.
USAGE
Here an example:
In the Script FvwmScript-Menus you first start the background program, here fvwm-themes-menuapp, and you set some variables for an easy use
of fvwm-themes-com:
# found the FvwmScript pid
Set $CMD = {perl -e '$t=getppid; print $t . "
"'}
Set $PID = (GetOutput $CMD 1 -1)
# Run fvwm-themes-menuapp until the end of the script
Do {Exec fvwm-themes-menuapp --com-mode --com-name=menuapp-}$PID{ &}
# to send fvwm-themes-com command
Set $SendMsgAndGet = {fvwm-themes-com --name menuapp-}$PID{ --lock-and-get --message=}
Set $SendMsg = {fvwm-themes-com --name menuapp-}$PID{ --message=}
Set $GetLine = {fvwm-themes-com --name menuapp-}$PID{ --get-buffer --line=}
Then in the Script you can ask fvwm-themes-menuapp for some informations:
# Get the menu list
Set $CMD = $SendMsgAndGet{"menu-items }$MENU{"}
Set $ItemsList = (GetOutput $CMD 1 -1)
ChangeTitle 11 $ItemsList
You can also just send an instruction to fvwm-themes-menuapp:
Set $CMD = $SendMsg{"exit"}
Do {Exec }$CMD
Of course your back program have to support the fvwm-themes-com protocol. See fvwm-themes-menuapp and fvwm-themes-config for examples (com-
mode option). See also FvwmScript-Menus and FvwmScript-ThemesCenter.
