--- Comment #4 from Jeff <junk.jsmith+kernel.org-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> ---
I should also add that my assumptions about watch descriptor reuse may very
well be overly cautious. If there is a guarantee that a wd will never be
returned by a inotify_add_watch() call until nothing with that wd remains in
the read queue, clients could handle deregistration semi-synchronously by
knowing to drop locally unmapped events.

This is something that I've not investigated recently, and I am completely
uncertain of any guarantees, but the kernel folks may have already done this
and just not passed the information along to users.
