Reword this to match the new world.

Would it be worth renaming the class and methods to match that too? e.g.
ManagedMode --> ManagedUserLock
EnterManagedMode --> LockManagedUser
LeaveManagedMode --> UnlockManagedUser
that kind of thing?

[Bernhard Bauer, 2013/01/15 14:24:44]

Reworded it a bit. For now though, there still is a managed mode, so I'd like to
keep the rest of the comment until we remove the class entirely.
Sounds good, but probably for another CL?
