Sometimes (when a read happened to end on a chunk boundary) the proxy

Sometimes (when a read happened to end on a chunk boundary) the proxy
would just hang trying to read a CRLF that did not come (remaining==0
because end-of-chunk, not because chunksize==0).  Also, when it
received its data from an upstream proxy which did not really support
HTTP/1.1 but claimed it did (ICS, Squid, both using nonstandard
Proxy-Connection: headers), Apache would not clear out the
"Transfer-Enconding: chunked" header and failed to correctly serve the
request.
