The lock should have already been released when the connection was closed.

If it was then releasing it again causes a "releasing an unheld lock" warning
on NetWare.  To avoid the warning, first try to get the lock before releasing
it.  The other alternative would be to just assume that the lock has been
released when the connection was closed so do nothing.
