I haven't found anything to do that.

This wont help you now but I ran across this problem a few times over 
the years with Fedora, RedHat, and the latest time on CentOS installing 
a fresh copy of 4.2 and then just doing an update a few months ago.

My solution was to create a script that did a 'yum check-update', parse 
the output, and then automatically do a yum update for each package one 
by one that was listed.  This made sure that if an update failed after 
installing but before the cleanup stage it would only affect the one 
package that was being updated(and its dependencies of course).  Doing 
things one by one like this I have never experienced the fail before 
cleanup problem again though.

The script is not very advanced so it would try to update packages that 
might have already been updated by dependencies earlier during the 
script run-time but it just ignores any responses that said a package 
was already installed(or nothing to do).  I had to run it 2 or 3 times 
for it to upgrade all the packages but eventually there were no more 
packages to update and I did not experience any problems.  This was 
after repeating the failure after 2 formats.

I wish yum had an option to do this.  I would call it 
--cleanup-after-each-package :).

Any time I do a update that will pull in a bunch of packages(like an 
upgrade) I use the script.
