Not in general!
Generating a multipart/* body (which has mechanisms already in it
for describing the length of each part), and then wrapping all that
in an HTTP 'Transfer-Encoding: chunked'. It's not that we think it
won't work or even that it would never be the right thing, just that
in the application environments we are targetting it is too
expensive in code complexity to be supported by default (code size
is _very_ important to our customers; our 1.1 server can be under
