So the GUI based interfaces are actually asynchronous, rather than the
psuedo-async that we do for the console?

I all sounds pretty good and sensible to me.  I'm a tad concerned
about how well Slim-vim would handle partial messages - I suspect that
it wouldn't.  We may need a tad more handling to ensure that only
whole messages are pulled from the Gray stream.  Of course, we've
survived so far, which means either:
1) We only ever get whole messages to work with from Swank
2) Partial message handling already "just works"

I'm happy with what you proposed.  I've had almost no time to geek out
lately, so I've done pretty much no Slim-vim work.  Perhaps this
weekend.
