OK, that is what I proposed.

What do you mean by "native wait or suspend"?  When entering blocking
OS calls such as os.wait, or even the stdio IO code, Python tries to
release the interpreter lock, to enable other threads to run at the
same time.

Because it is very hard to fix without slowing down the interpreter
for the single-thread case.
