No, it doesn't mean that.

But all the messages and signals circulate in a since thread (on a single 
cpu) unless you use special tools to split it into several threads.

Then there is the "client process", which "own" the patch windows and the 
main window. This runs separately.

Also, [soundfiler], some GEM input/output classes, and much of PDP, can 
run in an alternate thread.

No idea... I still run a single-core all day long.
