Description of problem: Currently when dnf holds a lock on its data and a second dnf process gets to the point where it is ready to update data, the second process will exit. It would be more useful for that process to wait until it can get a lock on the data and then proceed (which is what yum does). If this can't be the default, having an option to request that behavior would be nice.
Michal, you have fixed this, right?
