The ok_to_send() callback for in_pipe2 should only occur if in_pipe2
was (partially or fully) drained.  I'm just making sure you're not
saying that the activity on in_pipe1 is causing the ok_to_send()
callback on in_pipe2.

Yes, this is correct.  And as you said, the ordering of the callback
invocations is undefined.
