Ion, you'll have to fix the names. We went through a fair amount of work 
to make it possible to run test in parallel. It's an important feature 
as it reduces testing time considerably, even if you only have 1 CPU.

Note, it may not only be for different compiler versions. If you have 
different tests that can clobber each other, it's possible they will 
clobber each other when run on a single compiler test run is they tests 
run at the same time.
