actually setting them to exactly the same value is probably a bad

in store.c:storeExpiredReferenceAge(), it makes the following evaluation:

 (store_swap_high - store_swap_size) / (store_swap_high - store_swap_low);

which would then amount to dividing by 0. (Incidentally this then dies
on FreeBSD as it seems to change the values to float somewhere in
order to do the division).

I know that someone suggested doing it, but they were probably lucky
as to what their system evaluates the division by zero to, in this
context. Most come up with 0 or maxint.
