This should solve it in a robust manner:

my $actual_sleep = exists &CORE::GLOBAL::sleep    # already overridden
+ ?
                 ? \&CORE::GLOBAL::sleep
                 : \&CORE::sleep

Point is you are changing sleep globally, but some other modules might be trying to do the same thing already. (well ...)

If you install your override later, you'll be playing safe.

update

even more robust with defined instead of exists , see Haarg's comment in this thread for details.
