You are saying the script is not terminating right after the interrupt is issued?

I took your code and added a sub that i can test and also changed your TERM to INT so it is easy for me to test

#!/usr/bin/perl -w

use constant MAX_ITERATIONS => 1000000;
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 {
    $exit_requested = 1;
    print "Caught interrupt\n";
#   exit(0) if !$handling_request;
}

sub handle_request {
    print ("hi: $iterations\n") if $iterations % 10000 == 0;
}

$SIG{INT} = \&sig_handler;

# init();

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

print ("Exit value: Iteration = $iterations exit_req = $exit_requested
+\n");

Output Here when I run the script and hit ^C while it is running I get this output

hi: 0
hi: 10000
hi: 20000
hi: 30000
hi: 40000
hi: 50000
hi: 60000
hi: 70000
hi: 80000
hi: 90000
hi: 100000
hi: 110000
hi: 120000
hi: 130000
Caught interrupt
Exit value: Iteration = 133660 exit_req = 1

Seems to suggest that it picked the interrupt and terminated the loop at that point.

Is this the behavior you want and you don't see that? Are you sure you are sending TERM signals?
