Kirk McKusick? Keith Bostic? Mike Karels? At least ONE of those people
knows about Bstreams...
[Chris (Torek), how about you? Any ideas?]

See above.

* What do you mean about disconnect being sluggish..
Well, the STREAMS tty/pty driver is quite evident on Slowlaris (up to
and including 2.4). It always annoyed me that it sat there for up
to a second after printing "Connection closed" at the end of a session
before it gave me my prompt back.
Connect thru STREAMS is also less than optimal. Pushing all the required
modules atop the STREAM head costs some time. I may be overreacting to
all this and should probably just shut up and accept it, but I can't get
over how much faster it is connecting to/disconnecting from a
non-STREAM-based interface. This is most evident if you're frequently
running things like r{sh,dist,cp} and the like, and I find it quite
annoying.
Throwing faster hardware at slower software is NOT an option.
