While you are at it, POSIX requires an update to underlying file's ctime sometime between mmap(... MAP_SHARED, PROT_WRITE ...) and the corresponding munmap() or msync() if the mapped region was written to. If Windows correctly updates mtime on a mapped file, then one possible way to do this might be: when munmap()ing, if mtime is newer than ctime (but less than or equal to now), adjust ctime to match mtime. - -- Life is short - so eat dessert first!
