-This considerably reduces the time needed to perform the valgrind
-memory tests on systems with multiple available processors. In the
-case of my laptop, the duration was reduced from ~200s to 90s.

-Subject: [PATCH 6/8] Add ModuleIndexMerger.resolve_ext()
-
-This will allow us to handle default streams strictly when merging. In most end-user
-cases, we want default stream conflicts to simply drop the default stream (this is
-fail-safe). But when we are creating a repo with defaults, we want to be stricter and
-ensure that we aren't producing a repo with inconsistent data.
