Short-term:

Bugs:

        - Sometimes it picks a middleman node as the exit for a circuit.

        - if you specify a non-dirserver as exitnode or entrynode, when it

          makes the first few circuits it hasn't yet fetched the directory,

          so it warns that it doesn't know the node.

        - make 'make test' exit(1) if a test fails.

        - fix buffer unit test so it passes

Short-term:

        - when you hup, rewrite the router.desc file (and maybe others)

        - consider handling broken socks4 implementations

        - improve how it behaves when i remove a line from the approved-routers files

        - remove per-connection rate limiting

        - Make it harder to circumvent bandwidth caps: look at number of bytes

          sent across sockets, not number sent inside TLS stream.

        - make 'make test' exit(1) if a test fails.

        - fix buffer unit test so it passes
