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 ftpmaster does *not* delete outdated and no longer referenced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.
