Is it allowed for one to do a zero-byte RMA operation on a window of size 0? I couldn't find any wording in the standard that disallows this. If I missed something in the standard, I'd appreciate someone pointing out the page/line number specifying it.
The reason is that checking for this adds an extra branch on some networks, which we are trying to avoid.
