If you really need to reclaim memory from a big hash, fork off the code, and let the fork do the work. When the fork's pid is terminated, all memory will be returned to the OS. It is a little more complicated to fork things off, but you get complete control over memory being returned.

See Parallel::ForkManager and IO::Pipe for some helpful modules.
