 Atm. it's the FC7 GA yum, recompiled on FC6. Some of this might be that
my desktop is currently "relatively old".
 Doing "time yum list foobarbaz" (as a normal user) pretty consistently
gives me over 16-17 seconds (with maxed out CPU, mostly in user space).
 "yum list 'foobarbaz*'" actually gives me ~20-21 seconds, which was a
surprise (again 90%+ CPU).

 Well I had assumed that more than just the cli would want it, so the
change would be to do:

    def searchGenerator(self, fields, criteria, most_relevant=False):

...and put all the logic in there and return what we are now.
