Unfortunately, perl is quite liberal with memory, so from personal
experience: have as many "my"ed variables as possible, undef things as
often as possible, and remember, that perl doesn't release memory, just
recycles it, so once it takes from the system, that's it until the end
of execution, so be careful as to how much you let it grab.
Have fun :)
