Mine hangs because it's shutting down Firefox (Nightly from their
website these days).

Just as example, if I log out then log back in and run "ps aux|grep
firefox" after logouts that take a long time, there will most likely
be a long list of associated PIDs still in operation. If I try to
launch Firefox at that moment, it will most likely fail with an
advisement that a Firefox instance is already running. If I wait a few
more seconds then try again, Firefox will FINALLY have shut down the
rest of the way.

It's been ages since I first realized that was occurring. It was an
eye opener into that there's still a lot to learn about how operating
systems and their packages work under the hood. :)
