Miss Islington (bot) e60e7bdc92 [3.15] gh-159652: Fix import lock leak when the C stack is nearly exhausted (GH-159660) (GH-160779) ... gh-159652: Fix import lock leak when the C stack is nearly exhausted (GH-159660) When an import failed with a stack overflow RecursionError, releasing the import locks on the error path could itself raise RecursionError, because the cleanup runs in a new C frame. This left the global import lock or a module lock held forever, and later imports in other threads blocked indefinitely. _imp.acquire_lock() now raises RecursionError when there is not enough stack left to release the lock. importlib calls it before taking any import lock, so this covers the per-module locks too. The module lock weakref callback skips cleanup in that case instead of reporting an unraisable exception.
