Look at the source for TnFXApp::run() and FXApp::run(). Basically it
runs via getNextEvent() and dispatchEvent().

See above.
If you wish to invoke some synchronous call which isn't threadsafe,
you should set up a message handler which receives async messages
from other threads and executes the required call. I personally would
have it pass a BoundFunctor such that any thread can invoke any
function in any other thread arbitrarily. I have an implementation of
this actually in Tn but not TnFOX - it wouldn't be hard to port over
though. I might add that to the todo list actually.

I'd prefer the mailing list so others can search it in the future.
