e8579ed24a LibThreading: Wake up the background worker thread when there's work
The worker thread used for BackgroundAction was going to sleep for
1 second at a time (when there was nothing to do.) This made using
background actions for anything interactive quite unresponsive since
you had to wait up to 1 second before it even started on your task.

We now use a simple Unix pipe to signal the worker thread that a new
work item is available.

This makes Assistant way more responsive when typing. :^)

48731e9f17 LibThreading: Add new detach() API to Thread
Sometimes you don't care about `joining()` the result of a thread. The
underlying pthread implementation already existed for detaching and
now we expose it to the higher level API.
