You mean something like:

  dd if=/dev/zero of=/dev/null bs=256m count=2

? :-)

If you have more than about 512Mb of RAM, and it doesn't work, run a
few of these in parallel, till you hit somewhere between 1/2 - 2/3 of
RAM.  dd allocates a big buffer and overwrites it - twice, to try and
encourage it to stay in core over other programs' idle pages.
