I think this ties in with the whole issue of not having nightlies/test
bots running. I think if the infrastructure for that was in place then
this would simply be a part of the functionality.

re: subset of benchmarks, I believe they are just regular tests, in
which case you can explicitly pass in which test cases should be ran.
Correct me if I'm wrong.
