In the following code:

sage: R.<X> = QQ[]
sage: 2/(2*X)
2/(2*X)

Is there a case against simplifying 2/(2*X) to 1/X? If it is a bug, it 
seems to me that we need a new set of "non_monic_gcd" functions for all 
ring element classes that uses generic reduction (or is there a less 
invasive solution?). On the other hand, If there's such a case against that 
simplification (speed, no need to simplify, why does it matter, etc) please 
enlighten me as well, because It's making my function field computations, 
exponentialy slower, as my fractions grow into scary objects as time passes.

Thanks.
Syd
