Even if it can't, it shouldn't hang. It could signal an error for any
operation that needs a file descriptor, but it shouldn't hang. Then
the user could kill one of the buffers under auto-revert, or manually
switch to not using notifications, and be able to continue the
session.
Btw, my recommendation is to turn off auto-revert-use-notify in any
session that uses global-auto-revert-mode. File notifications simply
don't scale up well enough for that, given that Emacs sessions tend to
run for many weeks and have many hundreds of file-visiting buffers.
Also, if you somehow end up visiting a file in /tmp, your Emacs will
get notifications about every temp file operation on the OS, which
will probably slow it down quite a lot.
