I have recently learned that free() (or g_free() ) does not return
the freed memory to the operating system until after the program is
killed. So if I g_malloc() a ton of memory, and then g_free() it, my
program is still using a crapload of RAM until it is killed.
Is it any different with a GAllocator? I.e., if I need to
temporarily allocate a ton of GNodes, and hence push my own GAllocator,
after I pop that GAllocator will the O.S. get the memory back for other
apps/disk caching/etc.? Or is that memory *still* eaten up until after my
program is killed?
Also, the same question for a GMemChunk. If I call
g_mem_chunk_alloc() followed by either g_mem_chunk_free() (or
g_blow_chunks() ), is the memory still used up until my app dies? Or does
it somehow, magically, go immediately back to the O.S.?
Thank You,
