I have to confess it was partly measurement error as I had not rebuilt
the extensions in the branch with the annotation patch.  But it's
still about a factor of 7x, and enough not to pay it unless we have
to.

I'm going to put in the conditional and send this to pqm.  Once the
rest of stacking is in we'll need to reevaluate performance in that
situation.
