Hi Tom,

Thanks for the reply and the clarification. AFAIK the builds are
already running single threaded although I am not 100% sure.

I managed to get the i386 and amd64 builds done this time by retrying
the failed builds one more time. I guess I was lucky the third time.
One solution might be to set up own PPA builder but I'm not quite
there yet.
