Eh... not sure what you mean. If you are talking about how SM upgrades
itself - then that is a "custom" solution since it must be able to do so
even though it can't download a new map (since it is old, moment 22).

Well, there are always "ways" but I really want to keep SM in one piece
as long as possible due to reasons I have already explained. And as a
sidenote I can mention that Avi does exactly the same with Monticello -
he also checks what to use - just see senders of #logChange:.
