I spoke too soon.

pyinotify still seems to max out my number of user watches... I get
this message when I run inotifywatch after a pyinotify operation:

Establishing watches...
Failed to watch .; upper limit on inotify watches reached!
Please increase the amount of inotify watches allowed per user via `/
proc/sys/fs/inotify/max_user_watches'.


Strange. I'll keep on troubleshooting.
