Comment (by nickm):

 Re multithreading:

 I'm pretty sure this stuff isn't reachable from other threads, but it
 would be nice to clean it up anyway in case I'm wrong.

 Re error handling:

 It can't hurt to assert that the return value is non-null, though we could
 never reach that point in the Tor code if the base were absent.

 We should check the return value of tor_event_new, but event_active()
 shouldn't be able to fail.

 I like the assertion idea too.
