You'll have better luck with: 

exec $^X, $0, @ARGV
    or  die "Can't restart self: $!\n";

Other hints: Don't destroy @ARGV when you process it. Have the signal handler set a global that the main loop checks for so the exec doesn't interrupt some unfinished operation. It can be wise to have a long-running Perl process do this on a regular schedule even without having to be given a signal as it can reduce the impact of whole classes of bugs that you are unlikely to ever run into other than with a very long-running process.

See %SIG. Sadly, that bit of documentation doesn't appear to contain the very useful link that is included at the bottom of the kill documentation (so also follow my last link so you can follow its last link as well).
