I think this patch might have also the following two issues:

- Doing intense computation in a Lisp thread usually make the system
  extremely unresponsive, and it does it certanly if the code does not
  yield.  As the byte compiler never yields the 'blocking' effect should
  be the same as running in the main thread, this because this Lisp
  thread is never preempted.

- What about if the file being compiled is loaded before the byte
  compilation is completed?  This is another tricky part that has to be
  addressed (as we had to do in the native compiler).
