So this is subtly different than what needs_restaring does. This gives 
back a list of pkgs which own something which a running process has open.

So you can pre-emptively say:
   this process is in use, are you sure you want us to apply the update..

so something like yumex or PK, could tell users "you want to update 
firefox and it is running, how about we close it?"
