One possibility would be moving the rails directory to be a sibling to
micro and macro.
Another might be running it like PATTERN=macro-benchmarks/* and it
would avoid [?] rails?

I agree--it's more of a "system" benchmark than anything.
A sibling seems the right thing to me. It makes it more visible to anyone starting to look at RBS. I think Rails is certainly important enough to deserve a category of it's own rather than being a subdirectory of macro-benchmarks.
