POSIX_FADV_VOLATILE

Overriding this call seems wrong to me. In my opinion a new flag to mmap would work better. Then the entire mmap range could be cleared, fixing the potential problem of losing one page from the middle of an object.

Kernel to process notification?

This solution still needs a way for the kernel to let the process know when it's memory was relinquished.

POSIX_FADV_VOLATILE as a corresponding call for this task and it would be better overall if this lock/unlock||unPOSIX_FADV_VOLATILE/POSIX_FADV_VOLATILE didn't have many options.
