Yes, it sucks. I'm a fan of long-running daemons exec()ing themselves from time-to-time even if they weren't written in Perl. And you can usually handle quite a few signals before you get bitten.

With luck, someone who follows perl5porters more closely than I will chime in and note that certain bits of Perl's code have been protected from signals recently. Otherwise it may be Perl6 before a complete solution appears.
