Extracts? 

Also, maybe you want to pass in the Analyzer, rather than a file path. That way,
I'd guess this thing will work to scrape from a crashed process too?

Done.
I think that will happen from the filename (it's derived from pid+creation
time).

+CollectionStatus Collect(const base::FilePath& stability_file,
+                         StabilityReport* report);
