New submission from Christian Heimes: _PyImport_ReInitLock() doesn't check the return value of PyThread_allocate_lock(). A failed lock allocation can either lead to a NULL pointer dereference or to race conditions caused by a missing import lock.
As there is no way to recover from a failed lock allication I recommend to abort with a fatal error.
