Comment:

 Replying to [comment:245 cremona]:
 > Jeroen is right.  Almost all (and maybe all) the doctests in Sage which
 are tagged 32/64 bit are a result of this feature of pari's way of
 handling multi-precision floating point arithmetic.

 OK, fair point. Now I understand. I was under the impression 100 bits were
 being used.

 After applying Jeroen's patch

 {{{
 drkir...@hawk:~/sage-4.6.prealpha0$ ./sage -t  -long
 devel/sage/sage/rings/polynomial/polynomial_quotient_ring.py
 sage -t -long
 "devel/sage/sage/rings/polynomial/polynomial_quotient_ring.py"
          [30.1 s]

 ----------------------------------------------------------------------
 All tests passed!
 Total time for all tests: 30.2 seconds
 }}}

 I've set this to positive review.

 I copied all the authors to reviewers, as I think everyone that has wrote
 part of it has reviewed part of it. I also added Leif and François as
 reviewers, as they have contributed too. But I've not done an extensive
 search to see who should be on the reviewer and the author list. I suspect
 there are some missing.
