2607	For better POSIX semantics from Linux client, (even better

2609
2610	1) PosixCreateX - to set and return the mode, inode#, device info and
2611	perhaps add a CreateDevice - to create Pipes and other special .inodes
2612	Also note POSIX open flags
2613	2) Close - to return the last write time to do cache across close
2614		more safely
2615	3) FindFirst return unique inode number - what about resume key, two
2616	forms short (matches readdir) and full (enough info to cache inodes)
2617	4) Mkdir - set mode
2618
2619	And under consideration:
2620	5) FindClose2 (return nanosecond timestamp ??)
2621	6) Use nanosecond timestamps throughout all time fields if
2622	   corresponding attribute flag is set
2623	7) sendfile - handle based copy
