	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.

2024-09-19	shared/tinyusb: Only run TinyUSB on the main thread if GIL is disabled.	Angus Gratton
	If GIL is disabled then there's threat of a race condition if some other code specifically requests USB processing (i.e. to unblock stdio), while a scheduled TinyUSB callback is already running on another thread. Relies on the change in the parent commit, where scheduler is restricted to main thread if GIL is disabled. Fixes #15390 - "TinyUSB callback can't recurse" exceptions on rp2 when using _thread module and USB serial I/O. Adds a unit test for stdin functioning correctly in threads (fails on rp2 port without this fix). This work was funded through GitHub Sponsors. Signed-off-by: Angus Gratton <angus@redyak.com.au>
