Have you seen WWW::Mechanize::Sleepy? Personally, I use something along the lines of:
# Sleep a random interval between $duration and 2 * $duration - 1 unit sub rest { my ($duration) = @_; sleep $duration; sleep rand($duration); } sub fetch_page { my ($mech, $action, $target, $max, $duration) = @_; for (1 .. $max) { rest($duration); eval {$mech->$action($target);}; return if ! $@ && $mech->status == OK; } die "Failed to fetch '$url' after '$max' attempts\n"; }

Of course, if you want to allow for HTTP redirects then you will need to change status == OK to include acceptable HTTP codes. Additionally, if you use Time::HiRes to overload sleep, you can easily sleep for partial minutes. In truth, I typically use milliseconds.
