Patch #9 from Saem:

"Cut up the runPasses method into smaller pieces.  The small private
helpers should  be easier to deal with when code shuffling arising
from creating the new specialised batchers, not to mention, they're
much easier to understand.

I inlined them, in case function call overhead would be noticeable --
doubtful."
