I never have tried fork() here.   I use mod_perl and it seems silly to hold
a MP proc hostage for long running tasks,  I usually insert a command queue
into a database and have an external script (daemon) run the queue and
update the status/results.   This allows for very long running external
commands that are not imposing on your mod_perl config, and also has the
added benefit of allowing to distribute those commands across multiple
machines if need be.
