Very probably.  purge.log now ends with

   new_nrows=19342364 new_ncols=19185740 (156624) at 400.68
excess < 0.10 * #primes. See -required_excess argument.

The previous version had an excess of 1749.  #primes is ~53M so another
two or three iterations should be enough.

Thanks.  When I've finished this factorization and perhaps another one,
I'll put together a list of suggestions based on my experience with this
code and with other NFS implementations.   I may even be able to
implement one or two of them!
