I ... don't.  There seems to be the notion that since we're polling, that
shouldn't count against the runtime of the thread.  But the thread has
chosen to poll!  It is doing something!  For one thing, it's preventing
the CPU from entering an idle state.  It seems absolutely fair to
accuont this poll time to the runtime of the thread.  Clearly i'm
missing something.
