Well. The timeframe where this is possible should, if mirrors use the
right scripts, be close to zero.

We do two things.
1.) ftpmaster does *not* delete outdated and no longer referenced
    packages right away, instead they stay in their normal pool/ location
    for about 2 days. So even if its no longer in packages files it will
    be available for an additional time.

2.) Correct mirror scripts use a 2-stage approach in mirroring. First
    they mirror all but dists/, then they only mirror dists/.
    Naturally this second step is *much* faster, as its size is very
    Additionally the correct scripts also use --delay-updates, making
    the update to dists/ as atomic as we can ever have it.

As far as we are able to we are working against broken scripts and other
mirror synchronisation problems we know of.
