New issue 2061 by smichr: sqrt(-1.0*x) gives infinite recursion
http://code.google.com/p/sympy/issues/detail?id=2061
This happens because a test for coeff is S.One fails since coeff is Real(1).
as_coeff_terms/factors could be changed so only Rationals are returned for
the coeff. Then
(-3.0*x).as_coeff_terms() -> -1, (-3.0, x)
(-3.0 + x).as_coeff_factors() -> 0, (-3.0, x)
This would then treat Reals like pi and other such numbers since if you
replace 3.0 with pi above those are the results that would be obtained.
