Bit of a chicken-and-egg issue there. You don't want to call
demuxer::run unless there's work to do, but you can't know if
there's work to do unless you call demuxer::run to dequeue
events from the OS's event demultiplexer :)

This sort of use case is probably better solved using your
proposed windows message pump dispatcher, but I can also see a
use for short, timed invocations of demuxer::run.

Cheers,
Chris
