Sweep does two things:
- garbage collect whole database
- fix transactions states

I.e. immediately after doing sweep you do not need
to do garbage collection, so this is usual procedure:

fgix -sweep ...
gbak -g ...

(otoh, since garbage is already collected by sweep,
you will probably do not see any difference between
gbak with/without -g)
