I sense a misunderstanding. With "pushing" I was referring to
"uploading/publishing" a package to the repository on the master.
The mirrors were polling ad lib, at intervals at their preference.
I.e. when updating the master repository on the server, we emptied our
mirrorlists, and let the _master_ poll repomd.xmls from the _mirrors_.
When it found a mirror's "repomd.xml" was in sync, the mirrors was
re-add to our mirrorlists on the server.

This sounds pretty much like the same approach we had taken.

As I am heavily using mock, I am fairly often seeing this issue with
mock. With mock w/ rawhide I am even observing hard build-breakdowns
(Seems to me as if something in f21's mock was changed to not let it use

I can try - However, during some periods in recent weeks, these
incidents were so frequent, I'd not to anything else but filing tickets ;)
