Yes, this is what bothers me in user-lock case.
On the other hand contrib/user-lock' licence
cannot cover usage of LOCKTAG and LockAcquire
(because of this code is from backend) and this is
all what used in user_lock funcs. So, that licence
is unenforceable to everything... except of func names -:)
