Sure. But using the 'Lock()' method, a lock can be acquired which is
not automatically released. This is what I'm opposed to! It is an error
to hold a lock longer than for a very local scope. With a requirement
for manual unlocking, you will definitely get into trouble if
exceptions enter the picture. Thus, I would remove all methods which
lock a mutex without also ensuring that it is unlocked later. The only
way to lock a mutex would be through creation of an object which
releases the lock if it goes out of scope.
