So,

mittlerweile habe ich eine Lösung für mein Problem gefunden:

Ich setze den Signahandler auf IGNORE, dann kümmert sich das Unix um das aufräumen.

Code: (dl )

$SIG{CHLD} = 'IGNORE';

Quote
On most Unix platforms, the "CHLD" (sometimes also known as "CLD") signal has special behavior with
respect to a value of 'IGNORE'. Setting $SIG{CHLD} to 'IGNORE' on such a platform has the effect of
not creating zombie processes when the parent process fails to "wait()" on its child processes (i.e.
child processes are automatically reaped). Calling "wait()" with $SIG{CHLD} set to 'IGNORE' usually
returns "-1" on such platforms.

Kaum macht mans richtig, geht's ;)
