Comment(by arma):

 To clarify, I believe I added d0943987 when we had a test network all
 running on the same /16, and it couldn't handle my bridge. Since then, we
 changed routerlist_add_family() to not add any network-nearby family
 members if EnforceDistinctSubnets is 0, and it is 0 if you set
 TestingTorNetwork. So it would not be the end of the world to #ifdef out
 of the "try again ignoring families" logic, but I think if we #ifdef it
 out we will run across weird edge cases that only happen to bridge users,
 and I worry that 0.2.2 won't see enough testing for those cases.

 As an alternate fix, how about we change
 {{{
     if (!r && entry_list_is_constrained(options) && consider_exit_family)
 {
 }}}
 to
 {{{
     if (!r && options->UseBridges && consider_exit_family) {
 }}}
 ?

 That way we would skip the behavior when you set EntryNodes (good), but do
 the behavior if you set UseBridges (also good). After all, people aren't
 going to successfully be putting both their exit relay and their bridge in
 the same family (which might be a separate bug we should ponder).
