I see some time-out errors in VMD testing. The code makes heavy use of
the preprocessor but no single test should last more than 5 minutes (
300 seconds ).

I also would love to see time limit exceeded marked differently, and
maybe some way of having regression testers to increase the time limit
when those failures occur.

I think it is great work to have the regression test matrix marked more
