[PD] RE: audio click and windows firewall

hi all, 

having a firewall will affect the pd/gui communication as long as a
network socket is used. having a network socket will be a low latency
issue unless the network communication is done in a separate thread ...

the current implementation of pablio (that's used for asio / coreaudio)
is really bad ... i haven't been able to run safely below 25 ms of
latency ...
in devel, there is an implementation of a callback-driven scheduler,
that directly talks to portaudio without using pablio, giving MUCH
better latencies ...

if you need lowest latencies, i'd suggest, you try devel :-)

cheers ... tim
