Hi!

I'm having some troubles using eval and alarm in threads:
Code follows:
use threads;

my $thread = threads->new(\&mysub, $var1, $var2);

for (;;) {
  # here is an infinite loop
  # print seconds to see where it freezes
}


sub mysub {
  my ($var1, $var2) = (shift, shift);

  eval {
    local $SIG{'ALRM'} = sub { die("stop\n"); };
    alarm(10);

    while (1) { # infinite loop }

    alarm(0);
  };

  if ($@) { print "$@\n"; }
  return;
}

The thread is created and runs fine until the 10sec timeout.
When this amount of time is reached, the whole script freezes, and 2 or 3 sec after, it crashes displaying "Alarm clock".
Nothing is in $@.

perl -v: This is perl, v5.8.2 built for cygwin-thread-multi-64int

Any ideas?
Thanks!
