[Yum-devel] clean up sooner

[Neal Becker]

I got bitten today by massive FC5 rawhide update.  Because of a kernel bug, 
gcj-dbtool hung when trying to update.  I had to kill yum.  Afterwards, I 
could not restart yum due to dep problems.  I tracked this down to having a 
bunch of duplicate versions left.

I noticed when using smart-pm for update, that it does:

install x
clean x
install y
clean y


I wonder if yum would avoid some problems by cleaning old packages sooner?  
(I'm just guessing here that smart 'clean' means removing old package).
