Hi, Christopher!  This looks like good code to me; it is one of the
best-written feature patches I've seen in a long time.

Right now, though, the Tor development branch is in feature-freeze to
get ready for a stable 0.2.1.x release.  Could I ask you to remind me
to look at this patch again once 0.2.1.x is on a stable branch and
0.2.2.x development is underway?

(If people who want to use Tor from behind their SOCKS proxies would
try this patch out and let me know whether it works for them too, that
would be great.)

thanks again,
