but seriously, shouldn't there be an expectation that a single
HTTP request should get a complete reply, properly terminated,
within a relatively small amount of time, and that a continuous
entity body without termination (delivered through chunked encoding,
perhaps) is not a valid HTTP response?

If we don't disallow such things, a proxy implementation which attempted
to buffer complete responses before sending them on would be
non-compliant.
