I'm on Mac, and I've written a long script to open up a maximum of 20 Terminal windows and run a subscript with a different input in each of them. When each of these sub-scripts finishes, it changes the value of a variable ("$windows") by -1, which lets the main script know that it can open a new window. It's basically a brute force approach to parallel processing on Mac.
The problem is, when it reaches the max number of windows, it doesn't wait for the "$windows" variable to go down before moving to the next input. It just does the check and then moves on to the next input. For example, if I'm running a script called "subscript" on 50 files, it'll run the first 20, then spit out "Waiting for a window to free up" 30 times before exiting.
Can anyone tell me why it's not working the way I want it to? There is a piece of Applescript in there, btw. Here is the relevant excerpt from my script:

Dear Help,
Is it possible to continue the loop by going to the next available value, if the 'expected value' is not found. I have a list of values which might not get incremented by fixed value and hence the loop could break and the script could terminate.
Any suggestion is appreciated.

LEARN ABOUT PHP
set_time_limit
SET_TIME_LIMIT(3) 1 SET_TIME_LIMIT(3)set_time_limit - Limits the maximum execution timeSYNOPSIS
bool set_time_limit (int $seconds)
DESCRIPTION
Set the number of seconds a script is allowed to run. If this is reached, the script returns a fatal error. The default limit is 30 sec-
onds or, if it exists, the max_execution_time value defined in the php.ini.
When called, set_time_limit(3) restarts the timeout counter from zero. In other words, if the timeout is the default 30 seconds, and 25
seconds into script execution a call such as set_time_limit(20) is made, the script will run for a total of 45 seconds before timing out.
PARAMETERS
o $seconds
- The maximum execution time, in seconds. If set to zero, no time limit is imposed.
RETURN VALUES
Returns TRUE on success, or FALSE on failure.
NOTES
Warning
This function has no effect when PHP is running in safe mode. There is no workaround other than turning off safe mode or changing
the time limit in the php.ini.
Note
The set_time_limit(3) function and the configuration directive max_execution_time only affect the execution time of the script
itself. Any time spent on activity that happens outside the execution of the script such as system calls using system(3), stream
operations, database queries, etc. is not included when determining the maximum time that the script has been running. This is not
true on Windows where the measured time is real.

max_execution_time, max_input_time.
