Re: Is this a bug I see before my eyes?

See http://msdn.microsoft.com/en-us/library/xs8w4454(VS.80).aspx

It's basically a one shot that you've entered an Idle state for all
the OnIdle handlers.

If you want your handler to keep running, you can peek the message
queue at the end of our handler and run again. Though this may starve
out other OnIdle handlers.

I would run the background thread and set its thread priority to
THREAD_PRIORITY_IDLE.
