The native emitter will not release/bounce the GIL when running code, so if it runs tight loops then no other threads get a chance to run (if the GIL is enabled). So for the thread tests, explicitly include a call to `time.sleep(0)` (or equivalent) to bounce the GIL and give other threads a chance to run. For some tests (eg `thread_coop.py`) the whole point of the test is to test that the GIL is correctly bounced. So for those cases force the use of the bytecode emitter for the busy functions.
