I've got it compiled in now and will report back when it repros as
badly as it did originally.

I think I missed a zero on my original fresh emacs report. The report
of 1ms per for a long running emacs was correct though.
These should be accurate:
On emacs -Q I get 2 microseconds.
On a newly launched emacs w/ my config I get 3 microseconds with 9
buffers and 1 killed buffer.
On an emacs I've been running for a bit I get 40 microseconds with 71
buffers and 237 killed buffers.
