I found it. It's a bash-only feature, mind.

Code:
set -o noclobber

if ! exec 5>filename
then
        echo "Someone else already has filename" >&2
        exit 1
fi

# things writing to FD 5

killall5

KILLALL5(8)						Linux System Administrator's Manual					       KILLALL5(8)

NAME

       killall5 -- send a signal to all processes.

SYNOPSIS

       killall5 -signalnumber [-o omitpid[,omitpid..]]	[-o omitpid[,omitpid..]..]

DESCRIPTION

       killall5  is the SystemV killall command. It sends a signal to all processes except kernel threads and the processes in its own session, so
       it won't kill the shell that is running the script it was called from. Its primary (only) use is in the rc scripts found in the /etc/init.d
       directory.

OPTIONS

       -o omitpid
	      Tells killall5 to omit processes with that process id.

NOTES

       killall5 can also be invoked as pidof, which is simply a (symbolic) link to the killall5 program.

EXIT STATUS

       The  program  return  zero  if  it  killed  processes.  It return 2 if no process were killed, and 1 if it was unable to find any processes
       (/proc/ is missing).

SEE ALSO

       halt(8), reboot(8), pidof(8)
