thanks to david psenicka cm's real time scheduler now runs more
reliably in SBCL/Linux . the main change is that the rts thread is
now created by sbcl via a callback from c. rts now coexists amicably
with (other) sbcl threads and multiple sbcl threads can now sprout to
rts at the same time. its also now possible to use rr and fifo
scheduling policy without segfaulting. david also twiddled the config/
make process for linux so it should build ootb more reliably.
rts timing in sbcl is pretty good -- not quite as good as on openmcl/
darwin but certainly very usable! here is a pdf of a 12000 note
stress test running a musical process every 50 ms, just a few +-15ms
spikes.
