Yes

If you check out the CVS repository, you'll see that there are two new files,
lib/multi.c and lib/multi.h. They're the initial work material for the
upcoming multi interface.

You can broswe them LXR-indexed here:

        http://curl.haxx.se/lxr/source/lib/multi.h
        http://curl.haxx.se/lxr/source/lib/multi.c

They're not even close to working yet.
