I'm trying to test how long it takes for a particular module to load. I'm trying to use the following code: 
#!/usr/bin/perl

use Time::HiRes;
use Time::HiRes qw ( gettimeofday tv_interval );
my $iterations = 10000;

$t0 = [gettimeofday];
foreach (1..$iterations) {
  use my_module;
}
$elapsed = tv_interval( $t0, [gettimeofday] );

print "Elapsed Time: $elapsed\n";
print "Iterations: $iterations\n";
print "Mean Time: " . ( $elapsed / $iterations ) . "\n";

[download]
This seems to be only loading the module on the first iteration. Is there a way to force the module to "unload".

I know I could simply time the entire script running each time, essentially writing one script to time another script, but I want to avoid timing the parsing of the surronding Perl code, I just want the time for the load of the module.
