 Mobile phones are unstable and their IP changes all the time. Hidden
 services don't work well on them.

 Here are some things that can go wrong when the mobile phone (and hence
 the HS) loses network or changes its IP address:
 -  The circuits to the intro points get broken, the HS establishes new
 intro points and republishes its descriptor. Its clients are not aware of
 the new intro points, and keep on trying the old ones. This is #8239 which
 might be fixed soon.

 - The rendezvous circuits to current clients get broken, and the HS does
 not reestablish them. Then clients keep on trying the same broken
 rendezvous point on and on, instead of re-introducing themselves (or
 fetching a new descriptor entirely). We should verify that this behavior
 is broken, and think of better ones here.
