Actually its the association in the other direction which you'd want
to cache. It's fast given the commit SHA to dig the original patch id
out of the commit message. What is harder is given a patch id X, to
find all of the commits which either (a) have a patch id of X, or (b)
have a commit message indicating that the original patch-id was X. So
having a database which caches this information, so given a patch-id,
you can quickly look up the related commits, is what I believe Sam was
proposing, and which I think would solve the problem quite nicely.
