no clue what the policy in the Kernel is but --recursive-includes is
quite heavy handed as a default. I have one --recursive-includes still
running for Wine and it accumulated until now over 1126 CPU minutes
(Intel i5 mobile CPU with 2.4 GHz). It found 5 more cases while
--no-includes found 11 and --local-includes additional 32. The
--local-includes finished in less than 30 minutes (didn't time it exactly).
