I've never written a test for libcurl before but I'll take a shot at it.
Besides the doc issue I also have to look into properly handling this in
multi. Right now the hostpairs in each easy handle are loaded before
that handle's transfer but I think it would make more sense to load them
into the cache when they are added to the multi handle. What do you
think? This weekend I will have some time to look at these things, but I
doubt I will finish by then.

Thanks I am aware that inuse entries should not be modified and I had
accommodated for that in my implementation. See the comment block at
[1]. What I wrote in that first e-mail was my initial impressions. You
can see all the changes so far at [2].
