The PyMutex implementation supports unlocking after fork because we clear the list of waiters in parking_lot.c. This doesn't work as well for _PyRecursiveMutex because on some systems, such as SerenityOS, the thread id is not preserved across fork(). (cherry picked from commit 5610860) Co-authored-by: Sam Gross <colesbury@gmail.com>
