Description:
When a thread creates a thread with get_lock only that thread can release the lock.  There should perhaps be a way of a superuser thread to release the lock (maybe with a new kill_lock function).

How to repeat:
use get_lock() and try to remove it from another thread

Suggested fix:
implement kill_lock() to be executed as a superuser
