     Can't keep ts around, due to rpmdb.auto_close. BZ 622179.
     This kind of sucks as we have to remember in all future code not to
    keep a ts over any .rpmdb call, it's even better because almost nobody
    will hit it. It works though, and is simple.
    
     We could maybe fix this "better" by using a weakref in rpmdb, and doing
    it that way. Or having some manual way to mark auto_close as off. Or
    just rm'ing auto_close as a bad idea.
