I am forking a child process (a perl file is called in that child process)...
I'm not sure what you mean here. Do you mean that you are forking a child that is, in turn, forking a perl script?. When I run the following: 

#! /usr/bin/perl

    sub HANDLER {
        print "Got 'USR1'. Exiting with Return Code '110' !!\n";
        exit 110;
    }

$SIG{USR1} = 'HANDLER';
while (1) {
    sleep(60);
}

In background, and send SIGUSR1 to it, it immediately exits with code 110 (if only the HANDLER function had returned, the script would have continued to run).
