Even if it doesn't buffer complete responses, but just fixed size chunks,
it will still cause problems.

Apache's proxy is broken with never-ending server push connections.  I
suspect many others are as well.  What is needed is a timeout combined
with a buffer.  OTOH, that could still result in problems with server push
that sends a very small amount of data at frequent enough intervals to
reset the timer before the buffer is flushed.  I can't see any nice way to
do it aside from not buffering at all, and that is ugly.
