In a few places, I have got timeouts after adjusting the timeout value. This is most likely because I have used a timeout factor of 0.7 to minimise "flickering" behaviour before finally changing to a timeout factor of 1. One consequence of this is that a few test cases will have double the original timeout (those test that would not pass a reduction to 0.7). So in all the instances when the timeout factor is exactly two times the size, the reason is that I have realised that I have already adjusted the timeout and I do not want to quad it again.
