Thanks for the reply.  You mean you're happy to add a new-connection
hook, but not a context?

In an HTTP context I can work around that: my module maintains a
pool of connection contexts, and associates each new HTTP request
with its connection in a post_read_request hook.

Can I assume that if requests r1 and r2 come on the same connection
then r1->connection == r2->connection?  That would enable me to save
a little overhead by using the connection pointer as a hash key,
rather than having to compute a key from the connection data.
