Not really. The particular requirement you cite is afaik
doable if all opens are done with FILE_SHARE_DELETE. So
posix clients should always use that.
What we want to replicate is the trick that a file can be
newly created with a different identity while some handles
still have the old inode open. This right now would not
work, as we would not actually do the unlink(2) server-side
if there are still handles open. See close.c:183. So this
loop has to be modified to look whether all share mode
entries are posix-style.
Maybe we need to talk about this on the phone, but not
today. Its 10:40pm here :-)
