The only mmap that could have side effects on existing tests in the
_metadata one, but in fact it would reveal issues in tests, so at the
end I think it's a good thing.

I'd like "self" to not be conditionally shared but that would require
changes in several tests. Let's keep that for another release. :)

I also noticed that mmap() is already used in test_harness_run() with
results.
