Sam Gross 4256847190 [3.12] gh-125451: Fix deadlock in ProcessPoolExecutor shutdown (GH-125492) (#125599) ... There was a deadlock when `ProcessPoolExecutor` shuts down at the same time that a queueing thread handles an error processing a task. Don't use `_shutdown_lock` to protect the `_ThreadWakeup` pipes -- use an internal lock instead. This fixes the ordering deadlock where the `ExecutorManagerThread` holds the `_shutdown_lock` and joins the queueing thread, while the queueing thread is attempting to acquire the `_shutdown_lock` while closing the `_ThreadWakeup`. (cherry picked from commit 760872efec)		2024-10-16 14:03:32 -04:00
