If this is seen as a problem, the solution is quite simple
(this idea follows Jason's patch):

1) make pay_for_buildings not to sell any buildings. Instead allow
   gold get negative value (temporarily)

2) Add one more city_iterate_loop in Jason's patch, right after
   pay_for_buildings loop, which is executed only if gold is negative.
   It goes through cities and sells buildings if necessary (and returns
   upkeep-payment).

But the question is... How to make 2) to sell the most worthless
building? Simple iteration would mean, that algorithm would end up
selling all buildings in your capital first! (Most likely not what you
want ;))
