Is the thread supposed to do some additional work after being woken up?
If not, there is no point in going to sleep in the first place and the
thread should just terminate when it has completed its task. If yes, I'd
use a threading.Event object to .wait() on in the sub-thread rather than
putting it to sleep, and then .set() the event object in the main thread
when it's time to wake up the sub-thread.

Hope this helps,

Carsten.
