Ken Giusti commented on PROTON-401:
-----------------------------------

I see your point - I'll update the PROTON-200 patch to call drained as you explain in your
comment.

> If the sending link calls pn_link_drained() to indicate that it has send all pending
data, and afterwards it receives a Flow frame with drain=true from the peer, then the drain
never completes.
> The ordering is the problem: if the flow frame w/drain=true is received _BEFORE_ the
sender calls pn_link_drained(), then it works.
