thanks. I had to install lzip in /tmp, since it was not installed on the 
machine I tried.

With the gmp-5.0.0-20100123 snapshot (which still says "GMP 5.0.0" for
gmp_version) the "RES" usage is first at 1.7g, then goes up to 2.3g with
the program on

Thus I only see a small improvement with respect to 5.0.0, which took 2.4g max,
whereas 4.3.2 took only 1.6g.

It would be nice if someone else could confirm this, since it is not easy to
get a precise measure, unless somebody knows how to do without looking at the
"top" output.
