Comment (by nickm):

 I investigated a little, using dtruss (on osx) and strace (on Linux) and
 reading the source code (ugh, hairy).  Here's what I found:

 When you do getaddrinfo("\\") on osx, it sends a query to the network, and
 never gets a reply.

 But when you do getaddrinfo("\\") on glibc, it never sends a query to the
 network at all; instead, it recognizes early that the name can't be valid.

 So maybe this is not a Tor issue?
