\o/ Thanks for helping with this.

Folk that are interested in taking things further on this and some
related aspects...
 - we could look at ec2test using the parallel runner
 - we could look at premerge testing as Aaron suggests (I suggest
using Jenkins to avoid inventing infrastructure again)
 - we could just start landing with lp-land and back out things that fail
 - we could optimise the ~50% of the test run that is currently single
threaded and common to all workers - any linear reduction there will
give linear benefits
 - we could do the additional work to orchestra the test run across
multiple machines
