What I would do, is box the internal descriptor in file-notify-add-watch,
to make it unique to the caller and unbox it in file-notify-rm-watch and
file-notify-valid-p.  

A different question is, whether file-notify-add-watch should behave
like add-hook with regards to adding a function multiple times.  I don't
think it does at the moment, so I probably leave it as such (?).
