i doubt that ... pd is not a proper jack client, just renicing doesn't
the best latency i could achieve with the modified scheduler in pd,
that tries to make pd a proper jack client.

of you use pd with -rt, it will try to give pd realtime
capabilities ... but this doesn't really help, if jack doesn't have
if you need lowest latencies, i'd recommend, you check out devel, since
it reduces the latency by one io block size ...
but there are some design decisions in pd (it's better in devel, but
still not optimal), that will _never_ allow pd to become a very low
