Wot? It just takes a list which you can build any which way you desire.
The other option is to give it the full command line in a string, which
does work for this script (but not on Windows). If it finds shell
metacharacters in the arguments it'll run a shell, otherwise the forked
perl just does an execve.
If it's really the forking that is causing the slowdown, why not do
either of those things:
a) Generate a complete shell script and fork once to run that.
b) Open up two pipes to an "xargs -P $ncpu/2 L 1 …" and feed in the file
Getting the error codes back to the script and handling the error is
left as an exercise for the reader.
