For Timeout class, create a @contextmanager that switches Timeout with NoTimeout (empty context manager) so that if --gdb is set, no timeout will be triggered.

My bad, I should have tried it before.I think, just make mypy ignore it, like: Timeout = NoTimeout # type: ignore
I think I am going to drop this change.This series already has patch 2 to ignore another pylint warning, plus another separate patch was sent to silence a warning that pops out with newer versions of pylint.
So once this gets in, feel free to add a patch with this change. Emanuele
The reason for that is+ Timeout = NoTimeoutThey obviously have different types.+iotests.py:507: error: Cannot assign to a type+iotests.py:507: error: Incompatible types in assignment (expression has type "Callable[[], _GeneratorContextManager[Any]]", variable has type "Type[Timeout]")+Found 2 errors in 1 file (checked 1 source file)Any ideas on how to fix this? Otherwise I will get rid of it.
