Comment(by jdemeyer):
New timings using the same test files as before. Timings are best-out-
of-3 wall times. "baseline" is actually sage-4.7.2.alpha3 minus various
patches (#11587, #9138). "sage-4.7.3.alpha0" is a ''preliminary'' version
of sage-4.7.3.alpha0, including the new PARI (#11130) and MPIR (#8664).

This is '''some''' slowdown noticable in some tests, but it's not clear
whether it is real, as there is quite some variation of runtime with some
of these tests.
