I generated a list of the ~800 reused bug ids in the open forest.
Unfortunately, JBS was not very happy processing a "id in (<list of ~800
bug ids>)" query. I'll see if I can use different techniques to do some
analysis of the data.
As previously noted, the reused bugs ids are just lower bound on the
count of logical fixes which spans repos since some engineers, including
myself, opt to push logically the same fix to different repos under
different bug ids.
