Comment (by ilmari):

 RFC 2616 says "All 1xx (informational), 204 (no content), and 304 (not
 modified) responses MUST NOT include a message-body," so Content-Length:
 is not needed in these cases (and Apache does indeed not include it). This
 causes PassBody() to call pass_straight() with a NULL length argument,
 which waits until the connection is closed by the server. PassBody()
 should not call pass_*() at all for responses that are known to be
 bodyless.
