with this in mind, I think a new repo is needed on the main servers for
really hot security updates! That one could then have a 5 minute timeout
so that people aren't vulnerable for 8 hours. 

Hot security fixes could then be in this "hot" repo for a day or two
until 1) the mirrors are synced and 2) the 8 hours are finished for all
mirrors, after which the package can be removed from the hot repo again,
so that in the normal case, the repodata is just a few (empty) bytes.
