Regarding the timings, I consider the factor of 5 slowdown relative to version 7 to be acceptable considering all that is being done with the new routine. It is now doing everything short of factoring to keep things simple, e.g. an x**3 does not appear now in

```python
>>> (1/x+1/x**2).as_numer_denom()
(x + 1, x**2)
```
