        This would not really be an octave problem per se, this could have
happened with any other swap intensive operation, i would expect.

        I assume u are running linux. This might be an important thing to
mention on a linux mailing list, because this is more a kernel problem
then an application problem, IMHO.

        I used to have a problem where i would get a memory leak when i
did a lot of plotting from octave with gnuplot. It wouldn't crash my
machine tho, it would just run out of swap and kill octave and gnuplot.
That problem seems to be gone now, fwiw. ( this was on FreeBSD
2.1.5-RELEASE, with a 386/387 with 12meg of ram )

just my us$ 0.02
