Done! I also moved the authenticate code to work immediately both for
non-ssl and for ssl connect.

No problem at all. The rewrite was necessary[1] and I had to do it
someday anyway and this was an incentive to fix it now.


[1] As I said, or rather Stevens said, using stdio with non-blocking
i/o *is* a disaster waiting to happen. So it turned out for the best
since this is now out of the way and the monit httpd server has gotten
an overhaul (more cleanup is needed but now at least it should keep
together without duct tape.) Actually the server is pretty fast (ok,
it doesn't actually read and serve files, but it does other resource
demaning stuff and the following benchmark is not bad:
