2380         1) PosixCreateX - to set and return the mode, inode#, device info and
2381         perhaps add a CreateDevice - to create Pipes and other special .inodes
2382         Also note POSIX open flags
2383         2) Close - to return the last write time to do cache across close
2384                 more safely
2385         3) FindFirst return unique inode number - what about resume key, two
2386         forms short (matches readdir) and full (enough info to cache inodes)
2387         4) Mkdir - set mode
2388
2389         And under consideration:
2390         5) FindClose2 (return nanosecond timestamp ??)
2391         6) Use nanosecond timestamps throughout all time fields if
2392            corresponding attribute flag is set
2393         7) sendfile - handle based copy
2394         8) Direct i/o
