Description: Makes sure that __exit__ or __aexit__ is called in (async) with statements, by not handling interrupts during set up of the with block. We want to make sure that interrupts are always handled eventually, and ideally that they are handled promptly. Checking eval_breaker on backward edges ensures that they are always handled eventually. Checking after every explicit call ensures that they are handled promptly in most cases. https://bugs.python.org/issue29988
