Comment #4 on issue 2003 by smichr: Use factorint() with limit argument in
sympy/core/numbers.py
http://code.google.com/p/sympy/issues/detail?id=2003
Please see commit 2003 of the github/smichr/2003 branch. Changes were made
to the eval_power (to use a limit inside the trial factors routine) and
factorint routine (which now always checks for a perfect power).
Using factorint with a limit alone is not the answer to this issue since
factorint will still apply the more advanced methods, thus making
eval_power slow if large are encountered. And if you shut those methods off
then you are back to simple trial division...for which the Number's version
works fun.
