Comment (by haxxpop):

 Since we cannot close only some RP circuits, we need to close all RP
 circuits or not close them at all.

 If we close all the circuits, all the clients will know that torrc is
 reloaded.
 If we don't close them at all, we don't have a real client revocation.

 Another option is to have a torrc option to let the service owners decide
 by themselves.
