It would probably take less than a day to flesh out this idea and

what we're trying to avoid is committing new stuff that may require
additional cleanup, not cleaning up the stuff we already did
commit. Once we get to beta I'll be less enthusiastic about making
changes like this

+1 for fixing it, with full agreement with Robert's project
management perspective on the issue.

Having worked in this area a bit I definitely see the need in
general, and for auto-tuning we pretty much have to do this to get it
right. I think we should be edging into more auto-tuning
capabilities as we figure them out, making this all the more
important.
