I know that. And suffer from that, don't get me wrong but at least on
i386 the build times are often one order of magnitude slower than on my
similar bare metal on which, of course, I'm alone. It's often more easier
to get a bunch of oldish bare metal than have a server capable of
well supporting VMs at a reasonable performance. And I'm not even
mentioning SPARC bare metal versus virtualization for which I have not
enough experience.

Anyhow, the point is not this, the point is that we have stuff which
doesn't run on the lowest denominator that we support and that can be
quite surprising, even for me.
