If you are spawning processes and aren't waiting (or don't want to wait/watch) for them to complete (either by waitpid or another method) you can use

    $SIG{CHLD}='IGNORE';

to explicitly ignore SIG_CHLD signals. This will precent zombie processes from being created. (code taken from Perl Cookbook).
