Curiously, a quick test shows *all* the python routines as faster than fsolve. I found this surprising. Perhaps it would be worth the hassle of putting these in C, then again, function evaluations might be the bottle neck, although I doubt it.
Times are seconds for 10000 iterations,
f(x) = 1 - x**2 .
Initial estimate for fsolve: .5
bracketing interval for others: [.5,2]
