This is more complicated than just nffactor above, a few hours in this

from T = polredbest(A) [ will be monic ], and iterate polcompositum(T,T)
and polredbest() to obtain a "simple" (monic) polynomial.

gp 2.5.3, Core i7-3930k O.C. 4.2Ghz, 16GB RAM, after 65 hours this is
still running.

Any guesstimate on running time?
