A while back, I searched perlmonks and googled to get a better understanding of how perl manages memory. These are the links I've collected:

PM: Strange memory growth?
PM: Nested Calls, Recursion and MEMORY
nntp.perl.org - perl.perl5.porters (51374)
When perl is not quite fast enough
PM: memory usage/leaks
PM: memory usage woes
PM: Garbage collection of 'my' variables
PM: Tracking Memory Leaks
