I tried to recover from inconsistent "make replace" with pkg_rolling-replace
several times and always ended in a state with even more inconsistencies.
This led to rebuilding of all packages at least two times, and at least one
time I could get out with pkg_chk. In other cases I performed manual updates
to recover. This makes me believe that pkg_rolling-replace is not safe 
mechanism.

I still don't understand why it is recommended to recover from inconsistencies.
The way it functions (utilizing unsafe operations) doesn't make impression of
doing it correctly either.
