this probably get's a bit OT, but i really wonder:
let's say i am running pd on a multicore box running linux. let's say i
run several (two or more) instances of pd in order to distribute the
load on several cores, is it possible to run them all on the same
instance of jack? if yes, this at least would allow some kind of
userspace multithreaded pd.
