GC.free() usually works. Some memory allocators don't give back 
the memory to the OS, no matter what, until the process is over, 
despite that memory is free for the process to use in other ways 
(this is what often happens in Python on Windows).

If I am right, then if you try to allocate memory from the same 
program after GC.free() the total memory used by that process 
will not increase.
