Do not re-install the signal handler. That one little line of code has caused me a fair amount of pain in the past, on Solaris as a matter of fact. According to perlipc:

  But that will be problematic for the more complicated
  handlers that need to reinstall themselves.  Because Perl's
  signal mechanism is currently based on the signal(3)
  function from the C library, you may sometimes be so
  misfortunate as to run on systems where that function is
  "broken", that is, it behaves in the old unreliable SysV way

( the emphasis is mine ). Most systems people work on today are not broken. I know Solaris is at least one of them. FreeBSD is another. I would imagine Linux isn't either, but don't know for certain because I don't work on Linux boxen.

Follow tilly's advice.
