It puts your thread to sleep, until it gets woken up by the handle
you're waiting on being set to a signalled state.

Right. Just like select() puts your thread to sleep until one of its
files is ready (or it times out).

Do we have a terminology problem here?

The point is that, unlike classic Unix signal programming, you need
*something* that explicitly checks for the event. It could be a separate
thread in a tight loop, which is what the CONNX code appears to do, or
it could conceivably be something else in the main thread with a very
short timeout.
