unexpected behavior and even crashes. It should only be used during
extension module development.

If "disable_check" is True then the compatibility check will not
happen while the context manager is active. Otherwise (and by
default) the check *will* happen.

Normally, extensions that do not support multiple interpreters
may not be imported in a subinterpreter. That implies modules
that do not implement multi-phase init or that explicitly of out.
