well, I removed all the files in the tree under /var/cache/yum/x86_64/7 but
left all the directories empty. that got rid of a couple gigs of stuff.
among the remains, the only other big one remaining is:
2.3G abrt-di
which I won't mess with for now.
I've got 4.2G free, now, so that should run me for quite a while.
Thanks to all of you for your tips!
