Indeed, we have a bug open for this.


I think using `setproctitle` to modify what appears on the system
process list may be a better general solution (and it would let us do
things like showing `obfsproxy: obfs3,scramblesuit` in the managed use
case as well which I think is cute, if not massively useful.

As an added bonus it is a general solution that's more futureproof.
