michael goulish commented on PROTON-200:
----------------------------------------
I think this bug is a release blocker.
An implication, that is not immediately obvious, is that if you have one
receiver with two senders -- one of the senders will hang until the other
receiver calls 'stop'.
This makes it impossible to set up any topology except the simplest possible --
one sender, one receiver.
> [Proton-c] Credit distribution by messenger is not balanced across all links
