- If the server is spewing complaints about raising your ulimit -n,
we should add a note about this to the server descriptor so other
people can notice too.
-
- We need a getrlimit equivalent on Windows so we can reserve some
file descriptors for saving files, etc. Otherwise we'll trigger
asserts when we're out of file descriptors and crash.

- X <weasel> it would be nice to support a unix socket for the control thing.
- The main motivation behind this was that we could let unix permissions
- take care of the authentication step: everybody who can connect to the
- socket is authenticated. However, the linux unix(7) manual page suggests
- that requiring read/write permissions on the socket in order to use it
- is Linux specific, and that many BSD-derived systems ignore the permissions
- on the socket file. Portable programs should not rely on this feature for
- security, therefore the motivation for this feature is gone.

-R - clients prefer to avoid exit nodes for non-exit path positions.

- Automatically determine what ports are reachable and start using
those, if circuits aren't working and it's a pattern we recognize
