On my system (This is perl, v5.8.8 built for i386-linux-thread-multi) your script ran for many minutes, until I stopped it. I am running CentOS 5.2 with the CentOS distribution of perl.

Is it possible that your system is not running with safe/deferred signals (environment variable PERL_SIGNALS set to "unsafe")?
