* Limit the amount of memory that can be used for messages
using multiple transfer performative for a single message.
* New transport APIs to set and get the message buffer limit

* Any transfer using more buffer space will error

> Key: PROTON-2952
> URL: https://issues.apache.org/jira/browse/PROTON-2952
> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: proton-c-0.40.0
> Reporter: Andrew Stitcher
> Assignee: Andrew Stitcher
> Priority: Major
> Fix For: proton-c-0.41.0
>
>
> Proton currently has no limit to the amount of buffered memory that can be
> used for a message delivery. This is because deliveries have no limit to the
> number of transfer performatives that make them up and there's no way to know
> how many more frames there might be in the delivery, so proton will buffer
> every message byte in a delivery until it is used.
