I tried both of my code snippets before posting. My platform is Perl 5.8 on OS X: 

kyle@sulaco:~ $ perl -v | head -6

This is perl, v5.8.6 built for darwin-thread-multi-2level
(with 3 registered patches, see perl -V for more detail)

I did nothing to disable safe signals. The only part of what I actually executed that I left out of what I posted was my usual "use strict;use warnings;" (and I also cut out the "Use of uninitialized value..." warning that resulted).

I don't have a Windows machine to test on.
