One option is that we've already got a function in the code:
/** Go through the circuitlist; for each circuit that starts at us
* and is dirty, frob its timestamp_dirty so we won't use it for any
* new streams.
* This is useful for letting the user change pseudonyms, so new
* streams will not be linkable to old streams.
We could expose this function via the controller interface (maybe
as another signal), and then the controller could have a button to
"change to a new pseudonym." I think this was in the plans at some
point, but it fell off my plate.
This could achieve the goal of not overloading the network. Is it smart
to rely on the human to know when a pseudonym switch is required?
