No. Or rather the pdiff mechanism should be fixed to fetch all the
needed pdiff files concurrently and apply them in a single
pass. Alternatively the pdiff files could just not be made incremental
but that would modify them all on every update.


For a solution that works now:

Acquire::PDiffs::FileLimit "4"; // don't use diffs if we would need more than 4 diffs

You might argue about setting a suitable default for this based on
common network / cpu speeds.
