So each process has one inotify instance with just two watches. I was
under the impression that subfolders were also watched, but after testing
a bit, it seems to not be true. Only the SELECTed box is watched, right?

What confused me was that Thunderbird will show new messages in several
folders, but I guess it must be using multiple connections, one per open
folder.

Is there some way to have clients watch all folders? Server-side filtering
loses a bit of its value when you are not notified of the new mail.

I think max_user_watches is per instance, so should that just be 2?
