Please send me a patch against the debug cleanup stuff which you can
find in my tree (commit daf6d46c2467253af457b326e3299ea431dc2a94)
so that I don't have to go back over this stuff after the next merge
window to fix all the stuff people haven't noticed being queued for
the upcoming merge window.

Thanks.
