It seems to me that the proxy must only buffer as much as
the chunk is big.  If the chunk were extremely huge, then 
this might be a problem, but chunks should be small enough 
to be resonably buffered, I would think.

Of course, the chunk size doesnt give the robot any clue
how far along in the total content-length it is, 
the total length is still unknown. My guess is that 
the robot needs to make its own decisions about
how many bytes it will forward, or for how many 
seconds it will continue the transaction..
