Hi Dan. I'm showcasing the feature of this ticket in the release tour. The
above code doesn't look sensible to me, since {{{time eY=e(Y)}}} results
in a {{{ValueError}}} under Sage 4.0 and 4.0.1. Can you post sample code
to illustrate the timing improvement introduced by the patch? The code
should illustrate this both before and after applying the patch.
