as i understand it, the Dispatcher's conception and design is
predicated on shared memory access between the threads in
question. this doesn't exist (in any conventional sense) between
processes, and so the model is unlikely to convert very well. i could
be wrong, even very wrong. you're switching to IPC while coming from a
system that is using something really quite different from IPC because
of the shared memory ...
