Signals and Perl do not mix. Please do not use signals if a segfault
is not a desirable form of output.

One should not do anything as bad as that in a sighandler. What is
the failure rate you see? You may get slightly better rate (3% in my
tests) with something like
$SIG{ALRM} = sub { ++$state ; return };
and preallocating
$state = 0;
