But does that help those folks that are already using a version of cygwin
where mmap isn't working properly?

In an ideal world we'd have some test which would tell us if mmap was
broken. If it was broken, then we'd fall back to the old style garbage
collector. I don't know if that's feasible in this case or not.
And yes, there is a significant compile-time performance penalty for
not supporting mmap..
