* The number of live coroutines in a running interpreter: Implicitly limited by operating system limits until at least 3.11.
DOes the O.S. limit anything on a coroutine?
What for? As far as I know it is a minimal Python-only object, unless you have each co-routine holding a reference
to a TCP socket - but that has nothing to do with Python's limits itself: a couroutine by itself is a small Python object
with no external resources referenced - unlike a thread, and code with tens of thousands of coroutines can run perfectly
without a single glitch.
Of all limits mentioned in the PEP, this is the one I find no reason to exist, and that could eventually lead to needles breaking of otherwise perfectly harmless code.
(The limit on the number of classes also is strange for me, as I've written in other mails)
