* instead of making (dis)-allow 0.9 a property of connection info,
work off a state machine that engages in the liberal skipping of
junk before response headers only immediately after a no-content
response on the same connection.
* when scanning for response headers in a large amount of junk place a
non infinite limit on that (128KB).. the only known use case for
this is skipping illegal message bodies in 304's and those just
aren't that big.
