well, IMO message processing should be done in the dsp thread to have a
tight messaging/dsp interaction ...
however longer-lasting or blocking operations should be moved to a
separate thread

i started to implement a separation of realtime and nonrealtime threads
for devel_0_39, but mainly to be able to sync the dsp scheduler with the
audio driver (mainly portaudio). there is no real separation of
operations like object creation, gui interaction or buffer operations,
though ...
however, the synthesis engine, that i'm currently developing, takes this
into account ...

concerning realtime kernels ... taking the current implementation of the
audio backends of vanilla pd into account, running a -rt patched kernel
would have a similar effect as upgrading a viennese fiaker with a
formula 1 engine ...

cheers ... tim
