Comment:

 It would also be possible to make it harder for anything to accidentally
 mess with the routerstatus_t pointers in the nodelist between freeing the
 old networkstatus and making everything point to the new on.

 Also it could be possible to change the order in which the two operations
 happen.

 Also we could look at the stuff that caused the bug, and see if it really
 needed to look at the networkstatus list at all.

 Not in 029 though.
