This is a known issue.  The subvolume itself needs to be set read-only, 
and of course that can't be done when the whole filesystem is set read-
only.

But a read-only filesystem should be sufficient, provided it can be 
forced to remain read-only thru the entire send.  I think that's the 
worry, that someone will switch their system from ro to rw in the middle 
of a send, thus screwing it up.

But they're aware of the problem and should eventually have a fix.  But 
I'm not sure how long as there's other work going on too, of course.
