The issue mentions only receiving buffers, so this PR only changes those. However, there might be value in changing sending buffers as well. Happy to update this in a subsequent commit if needed.

Closes #350

Thank you for this, it looks like it's going to help quite a bit with memory consumption.

Lets discuss a bit the rpc thingie, and then I am happy to merge.

Also, lets do send buffers while at it; it can be a separate pr.

@vyzo, I am currently on the two-week team onsite, and it's almost the end. Going to bring this over the finish line right after.

The are some unanswered questions in the thread, IIRC

yeah, whenever you can.

I think reverting the eof change for now, or releasing the buffer, will do for merge.

But lets create a follow up issue to discuss the general handling and come up with a good solution that can later be speced for other impls to follow.

@vyzo, so I reverted the EOF change and started making an issue for it. Now it's only the reading side with pooled buffers. I can also try to squeeze in the write today if we want to.
