When malloc libraries release memory, they sometimes don't unmap it, but instead call madvise(MADV_DONTNEED). Such memory normally first stays resident, but is later discarded, instead of swapped, when some other process needs more memory. Is there a way to see the amount of committed (vs. uncommitted) memory for the process? Yuri
