Based on these results: http://hera.physchem.kth.se/~sympy_asv/refine/#refine.TimeRefine01.time_refine
it seems as the new assumptions are to blame: https://github.com/sympy/sympy/pull/2508

This looks like a nasty performance regression, 1000x slowdown from 0.7.5-git to 0.7.7-git, let's see how it looks on the test machine...
