It's more my non-workflow... when I cannot find a patch for some reason
(deleted by mistake, eaten by Gmane, etc.), I search it with Google and
sometimes spinics.net comes up which mangles the domain.  I should just
subscribe to kvm@vger.kernel.org since Gmane has gotten less reliable,
or set up a Patchew instance for it.
