So I thought about this. Could we send an email only after all tests
have finished? That would decrease email load substantially.
I believe we can, if we can live with some temporary hardcoded
definitions.
We know that we currently execute only two tests, depcheck and
upgradepath. Upgradepath runs always on a noarch arch. Depcheck runs
on i386 and x86_64 in 99,9% [1].
I just realized that upgradepath is not run for updates proposed into updates-testing.
Something to keep an eye on. Still it should be doable.
