I've implemented recursive watching for a few different projects. The way I've basically done this is:

• Add a watch for the root dir
• When there's a create event, walk the created dir and add new watches for all dirs
• When there's a remove event, remove the watch for that dir

(I'm using fsnotify.v1.) I've realized that this isn't correct, because I don't delete the watches recursively. So I guess I need to keep track of the full tree of watches on my end as well? Maybe fsnotify could help out by exposing a 'delete all watches with this prefix' method or something.

Suggestions?

Additionally, #40 means that even if I could know all the dirs to remove watches for, I still couldn't delete them.
