This is a more conservative patch which only saves importing the plot.* modules (about a 50-100ms savings on my computer).

Robert, did you even test this? It seems to fail doctests all over the place. E.g.,
sage -t devel/sage/sage/calculus/riemann.pyx ********************************************************************** File "/mnt/usb1/scratch/wstein/sage-4.7.1-sage.math.washington.edu-x86_64-Linux/devel/sage-main/sage/calculus/riemann.pyx", line 114: sage: m = Riemann_Map([f, hf], [hf, hfprime], 0.5 + 0.5*I) Exception raised: Traceback (most recent call last): File "/mnt/usb1/scratch/wstein/sage-4.7.1-sage.math.washington.edu-x86_64-Linux/local/bin/ncadoctest.p ... ImportError: No module named riemann
It seems like using LazyImport? in any nontrivial way always results in serious breakage that is revealed by doctests. I hit this numerous times myself. Hmmm.

Is anything happening on this? Robert wrote the patch, William says it breaks doctests all over the place, but then it just stalls.

That's another quarter-second (12.5%) savings.
