Well, it turned out to be easier than I had feared. I've now got a midi
input queue system that doesn't have to do any polling. The queues
notify any observers as messages come in. It will be easy, from here, to
add support for midi message filters on a per-observer basis, so we
could do things like... let the MidiMonitor be notified of all messages,
yet let SysexGetDialog only be notified of sysex messages, etc.

Another thing I plan to do soon is to add a "thru-filter". I'm currently
experimenting with a rackmount effects unit which seems to merge all
incoming messages through the out. So, when I request a patch from the
unit, the first thing I get back is the request I sent. I think I'm
going to have the midi sender keep a rotating queue of, say, the last 5
or so messages it sent out. If something comes in which exactly matches
it, it could be ignored.
