After a short while I got terrible timing problems with the Audio-Pd, including stuttering etc. If running with Jackd there also were Jack underruns, and often jackd killed itself or dropped the connection to Pd.
however you dont _need_ netsend to do this. i pretty much gave up playing with GUi widgets wen PD was connected to the jack graph, since a burst of traffic can usuaully get it kicked out of the graph _and_ get pd killed by its own watchdog.
but we all know single-threaded design is bad, and its not like i can code C without turning an uninhabited island to Segfault City, so i'll be quiet. :)
