vogar insanely slow because of excessive fs traffic

i finally thought to try ctrl-\ to diagnose my vogar slowness, and hey presto:

another win for poor man's profiling.

the temporary work-around is to comment out --results-dir in ~/.vogarconfig. 
the fix would be to check this once, at the end, not once for each outcome.

we shouldn't be blocking on this work; we can kick these off in parallel and 
have them running while we continue to run other tests.

I changed the structure of the test history files.
