XXX esi.vtc is subtly different in the expected
ReqAcct numbers, due to different response header
sizes. See the two XXXs in the VTC file.

This is *not* because of the header that shouldn't
be there according to the test, that's checked in
the test, and it doesn't appear in the log.

I suspect that this difference is irrelevant, but
have am going ahead with the commit despite the
uncertainty.
