Comment(by rbeezer):
Yes, I meant to bring this up in the flurry of noisy doctest fixes. I
have taken to not cutting it too fine on the zeros. For example, if I get
a "zero" on the order of {{{10^-16}}}, then I have taken to clipping zeros
at {{{10^-14}}}. There seems to be too much variability across systems,
so if you cut it too close, then some system is eventually going to
complain, it seems.
The latest patch looks good and applies and builds find, passing all tests
in {{{sage/ring/polynomial}}} on the alpha3-prerelease I picked up about
10 days ago. So ready to go, again.
