 assuming one launches tor like this:

 tor DataDirectory /tor ControlPort auto ControlPortWriteToFile
 /tor/port.conf

 and /tor doesn't exist yet, tor will warn that it couldn't write
 port.conf. It will afterwards happily create /tor, and if you rerun the
 command everything will work fine. That's kind of weird. We could decide
 this isn't a tor bug, and any path you pass to ControlPortWriteToFile must
 exist, but that's a bit inconsistent with our other *File options which
 will work that way, because they happen to be interpreted after the
 datadir is created. So I think we should decide this is a tor bug. Why are
 we opening ports before making our data dir anyway? Due to the need to
 drop permissions?

 Marking this as major as it blocks a new package release with Vidalia
 0.2.13
