The pool stuff is working. There are probably lots of quirks/bugs, but the
general structure seems right.
I did the pool stuff first because I found the code I needed while I was
cleaning out the old stuff. Normal host mode shouldn't be too hard.

One possible reason to use something else is to get the TTL from the
response. There is no way to get that with the normal API.
Other than that, I'll be real surprised if you want to drag in another
I think you said that c_ares uses a callback. To fit that into the
current/new structure, all we have to do is have the called-back routine save
or copy the data, then send a signal to the main thread. The main thread
will then call in to do the real callbacks in the right context.
These are my opinions. I hate spam.
