LGTM. Nicely done.

I could see a case for caching full SU results, instead of separates bits of the result and reduce calls to the SUs (the current PR will dupe calls to the SUs), but then we'd need to worry about the potential for more cache evictions, which could cause either thrashing or high memory pressure, depending on configuration.

Without further exploration, the approach in the PR -- resulting in dupe calls -- is most likely the safest bet.

Another approach, probably most ideal, would be to combine the caches into a single shared cache, key'd off process id and whose value would contain both the owner and module.

No dup calls to the SUs, higher cache hit rate, and deterministic doubling of memory usage, by the cache, which is fine since the cache is already limited to 1MM entries -> ~20MB max size.
