My patches don't seem to have had any effect.

Can you pick a unit test (eg RunCMake.TargetPropertyGeneratorExpressions) 
and find out exactly which commit is causing the slowdown from 1m55s to 
4m28s on the affected machine?

I think I've done all I can with guesswork and without access to an affected 
machine.

Thanks,

Steve.
