Thanks for the debugging. I am trying it out (sage -br takes many
minutes with this for some reason). If that works then I'll follow
your suggestion to move this polynomial selection somewhere else.
Should have a patch ready tomorrow...

You might want to check the NTL code for whether NTL "auto-detects"
that you have supplied a sparse polynomial (and hence uses faster
code for arith

Thanks, Martin. I agree with your comments. All I am really talking
about here is the time taken to construct the field -- I know that a
lot more work will be needed to get a really good finite field setup
in Sage (including arbitrary coercions into extension fields, as
previously discussed).
