Well I guess it would not hurt to have some things like low-latency
patches, etc. (linux has that after all :)))

I am sure it would make *BSD more useful. recently I had to program a
sound "pacemaker" (i.e. a heartbeat .wav is sent to the soundcard
regularly). So this is not real-time, BUT: since the rate was meant
to change constantly (ranging from 33 bpm to 120), I could not use 
/dev/rtc. Neither did the usleep() and nanosleep() function calls give me
the precision which I wanted. signals were useless.

Now some of you might wonder why I mention that sound not-even realtime
simple project: because with sound output you can immediately feel if
something is happening 100ms to late :)

So, to sum it up: maybe its not a priority for freebsd but low latency
things would sure make freebsd become more of a desktop multimedia OS
(seems we are going in that direction anyway with all the KDE great
stuff). Linux is going that way, why should not freebsd to some
extent? --> some realtime capabilities would be great.
