When the perl variable(s) that refer to the hash or array go out of
scope the memory is freed in the perl process. This means that perl can
reuse that memory for other things, but the memory is not returned to
the OS until the process exits. That's the normal behavior for just
about any OS/memory allocation system that I've ever used.
