What does smart do with any multiple "indexes" it downloaded
(in a single 'update') from more than one mirror ?   Does it
'merge' these "indexes" to create a master list of all packages
available for downloading ?   And when smart closes, is it this
master list, or the "index" from the *primary*, that is cached
for use with a subsequent independently invoked 'upgrade' ?
