I think you're missing to set up an exception handler in the new 
(remote) thread. The default exception handler in a new thread just 
terminates the thread upon error and exits the thread with the exception 
object being stored in the thread's data structure (so that thread-join! 
will be able to throw it) (I don't know whether termite does it 
different, though).

I've once looked up (in _repl.scm I think) how Gambit sets up an 
exception handler for this; hm taking a quick look, I see:

(set! ##primordial-exception-handler-hook ##repl-exception-handler-hook)

probably you want to use this one.

Christian.
