Simplicity? Why would a thread "move" between threads?

Whoa! Why would we want that? And if so, how would it work?

Gosh. Abandoning the cooperating multi-tasking of current Rockbox will open
all gates to hell and lead to no good. We'll need a bazillion locks, mutexes
and similar things and then still have to debug for thread-related problems
and dead-locks for many months/years ahead.

I'm strongly in favour of keeping our current simple threading system. KISS.
