I am facing the same problem. I've tested against Apache/2.0.48.

I'm glad to see that you've tested against other versions, and can
confirm my experience. Unfortunately, I don't have an answer for how
to fix this. I'd like to hear one.

Is this considered a bug for a feature? I can see how it might be
benificial to buffer chunks and send them along as a larger chunk,
for some applications.

It might be a missuse of HTTP to expect chunking to work this way,
but it would certianly make it easier on my particular application.
