Robbie Gemmell commented on PROTON-2255:
----------------------------------------
I'd agree it's much less consequential now we know what/why it happens. The
issue before was we didn't know, and it could have had much more serious
implications depending on what was occurring. It's also not a proton bug either
way it seems, which again we didn't know before looking. Still points to odd
behaviour from Dispatch (actually explicitly enabling a non-effective level of
session flow control when thinking/indicating it's basically disabled).
