By jakesmith:

There's an argument to say it should be renamed, as doesn't give exclusive rights to the caller, i.e. can call again, nested and re-modify.

But as I say it gives exclusive rights to the properties of the logical file that the IDistributeFile reflects.
Not sure what a good name would be, lockSDS() / lockDali() or something perhaps.
