Comment (by arma):

 Taking a step back: is this design the right one to encourage client
 applications to use? Basically you are wanting to disable much of the
 client-side onion caching logic.

 Is there a better design, like noticing when your network connection has
 been broken, and flushing all the client-side state right then, and
 otherwise letting Tor do its thing?

 Or better, we could improve the client-side caching logic to be more
 robust to whatever network behavior you're seeing? It is silly for each
 client application to have to do this logic itself.
