Reliable killing childrenby JaWi (Hermit)

JaWi has asked for the wisdom of the Perl Monks concerning the following question:
Hello fellow monks,
I'm currently busy with a graphical front-end for smbclient, which allows me to click-and-download files from remote Samba hosts. Downloading is done simply by `back-ticking' a smbclient command.
It is possible to stop ongoing downloads by sending a HUP signal to the current process group (as stated in the PerlIPC manpage). This feature works fine until I spawn my graphical front-end from another Perl script! The kill-signal seems to be ignored and the smbclient program keeps running.
Is there a reliable way to make sure a script can kill all of his children even if the script itself is a child?
Thanks in advance!
