I think we also want to make
enter_task,leave_task, andswap_current_taskbehave atomically. For example,enter_taskmakes two dict API calls that individually lock the dictionary, but the combined operation isn't atomic.I can think of two strategies for this:
enter_taskmay be able to usePyDict_SetDefaultRefandleave_taskmay be able to use_PyDict_DelItemIfwith some modifications.gh-121621: Use PyMutex for writes to asyncio state (#121622)
