Content
As per Nathaniel's comments on issue 29988 and 31388, doing this robustly relies on: 1. the event loop being able to reliably guard itself and __aexit__ method implementations against interrupts (issue 31388) 2. "async with" statements ensuring that if the frame resumes after calling __aenter__, then it will also call __aexit__ (as was done for synchronous with statements in issue 29988)
