I'm wondering if that indicates the problem is in an externally called
application, like git. I notice VC is being used, and if I copy the
lisp directory into a non-VC'd directory and run the test there it's
significantly faster.

For some reason I can no longer replicate the problem though, so I
can't check this idea myself.
