There are multiple lock manager RAII classes which take both OperationContext and Locker (or both) in addition to a deadline argument. The behaviour of whether the OpContext's deadline will be obeyed seems dependent on what combination is passed for these three. For example, passing OpCtx=nullptr, Locker, deadline=Date_t::max() will not obey the deadline of the operation, because the OpContext is not passed down to the waiting method of the lock manager.

We have runWithDeadline methods on the OperationContext which will allow us to not have to pass the deadline explicitly.
