That's not really a good idea. You could just set timeout option on the socket after creating it: 

use Socket qw(SO_RCVTIMEO);
use POSIX qw(:errno_h);
...;
my $timeout = pack 'L!L!', $sec, $usec;
$handle->sockopt(SO_RCVTIMEO, $timeout);
...;
my $res = $handle->recv(...);
unless(defined $res) {
    if($! == EAGAIN or $! == EWOULDBLOCK) {
        say "time out";
    }
}
