Prior to perl 5.8.0, signals in Perl are unsafe. This is because signals are handled immediately if they arrive, regardless whether the internals of perl are in a consistent state or not. Furthermore, lots of function (including many of the implicite functions, like looking at a variable) in Perl aren't reentrant safe.
