Not getting the desired behavior from the alarm function on WinXP Activestate Perl 5.8.6. It alarms at 1 sec, nothing greater. Reading the release notes I see where signals are handled after a operation is complete. So I guess this is expected behaviour or is something else going on here? Any sugestions on how to make a timer on my ssh session without using alarm()? 
use strict;
use Net::SSH::Perl;    #Use this perl mod to create the SSH session.
use Net::SSH::W32Perl;

my $host = "";
my $user = "";
my $pw = "";
sub error {
   die "ERROR! ERROR! ERROR! @_";
}

sub ssh_cmd{

    my $ssh = new Net::SSH::W32Perl($host);
        $ssh->login($user, $pw);


    my $cmd = "./test_alarm.pl > test_alarm.out 2>&1";

    my ($out, $err, $exit) = $ssh->cmd($cmd,"\n");
}


    my $TIMEOUT = 2; # seconds
eval {   
   local $SIG{ALRM} = sub { die "alarm\n" };   
   alarm $TIMEOUT;  
   ssh_cmd();
   alarm 0;
   };

if ($@) {
   if($@ eq "alarm\n") {
      error("OPERATION TIMED OUT!");
   } else {
      error("your_code() generated errors: $@");
   }
}
