It might make sense to redesign this stuff so that watches don't hold
references on the object being watched.

I explicitly made it hold a reference so that if you place a watch on an
automounted mount it stops it from expiring.

Further, if I create a watch on something, *should* it be unmountable, just as
if I had a file open there or had chdir'd into there?
