It is not a one line fix. It uses extremely ugly message queue between
http requester and session - ignoring the fact that one http connection
may be shared between sessions and there can exist backgound connection
without a session.

Subject: [links-list] HTTP auth in Links
HTTP auth is really buggy, I had to disable it in Links.
Go to www.freshmeat.net, click on 'lounge', press '<-' immediatelly, wait
until page loads in background, exit links => memory leak.
Go to www.freshmeat.net, click on 'lounge', press '<-' immediatelly,
select 'Flush all caches', click on 'lounge' again => segfault.
The problem is that you are assuming that connection has always session
attached to it. It is wrong. If the user cancel request, it is loaded on
background without session; if one file is loaded in more sessions, there
is only one connection shared between these sessions.
You should remove the test for authentication from http_got_header and
test for the need to authenticate in session.c - at the same place where
redirects are tested. Possibly also remove the question queue.
Also remove S_QUESTION. You have enough information about connection
(including full header), so you don't need S_QUESTION.
