Hi!
On Linux, Does MADV_DONTNEED (used in ReleaseMemoryPagesToOS) actually mark the
pages as free to be overwritten with zeroes? It seems that the POSIX
explanation of POSIX_MADV_DONTNEED means something different ("the system can
page the memory out, but not discard the content"). Darwin and BSD understand
MADV_DONTNEED in the POSIX sense, which means that ReleaseMemoryPagesToOS
doesn't really release any memory on those systems. Does it make sense to use
some other mechanism of releasing the pages?
