Doing "%prun TestSuite(M).run()" gives

This indicates that any significant slowdown must be from the generic
polynomial xgcd. There are no callees of that registered in the profile, so
digging any deeper probably means c-level profiling. The profile data does
not implicate the coercion framework at all at this point.
