Hi.

I have a Perl mini daemon that I would like to control as follows:

1) The daemon consists of a loop, which loops until either a counter is reached, or a TERM signal is received

2) When either of those happen, it waits till it finishes the current loop, then exits.

Number 2 does not seem to happen

Here is my code: 

use constant MAX_ITERATIONS => 1000;
use constant MAX_TIME => 600;

use warnings;
use strict;

my $start_time = time;
my $iterations = 0;
my $exit_requested = 0;
my $handling_request = 0;

sub sig_handler {
    $exit_requested = 1;
    exit(0) if !$handling_request;
}

$SIG{TERM} = \&sig_handler;

init();
while (!$exit_requested && $iterations <= MAX_ITERATIONS && (time - $s
+tart_time) < MAX_TIME)
{
$handling_request = 1;    
handle_request();
    $iterations++;
$handling_request = 0;
}
exit(0);

Why no work?
