stub: remove use of max_delay_us

Browse Source 
Ben's having to work around all of the max_delay_us code
in his thread/reactor refactoring.  Once we have a real
scheduler, this whole idea will need to be rethought.  So
for now, let's get existing code off of the max_delay_us
mechanism, so that we can remove it.

For the stub app, just add a poller that does a usleep.
This will have the same effect as the current behavior.
