still the same problem with this:

#!/usr/bin/env perl
use strict;
use warnings;
my $total_sleep_time = 0;
BEGIN {
my $actual_sleep = \&CORE::GLOBAL::sleep;
*CORE::GLOBAL::sleep = sub { $total_sleep_time+=$_[0]; $actual_sleep->
+($_[0]) }
}

# use this module and the other
# ...

sleep(2);
print "total sleep is $total_sleep_time\n";
