Comment (by teor):

 This appears to be an address resolution issue.
 Tor is hanging on this line of code in `address.c`:
 {{{
     err = sandbox_getaddrinfo(name, NULL, &hints, &res);
 }}}

 For some reason, almost every other name or symbol either gets resolved
 quickly, or fails.
 But `\` takes 30 seconds to resolve. The resolution is attempted even if
 `--DisableNetwork 1` is specified.

 I'm using OS X, in case this behaviour is restricted to a particular
 platform.

 The simplest command-line which can reproduce this issue for me is:
 {{{
 tor --verify-config --ORPort \\ -f /dev/null
 }}}
