I switched to fc4/64-bit (I think) from netbsd/64-bit and
openbsd/64-bit for the better apm support on the laptop, but I didn't
notice any great changes in how userland behaved.  The BSD's seemed to
handle large address space programs a bit better when they started
swapping, but it wasn't enough of a problem to force me back.  We are
talking about a program with a 13 gig working set and 4 gigs dram, but
with very good locality of reference.

I'm surprised that clisp hasn't been hacked to run on Linux/64-bit.
Back when I cared about such things folks were always drooling over
large sparse address spaces and how it was going to help all sorts of
aspects of creating lisp objects.  I'm surprised to see that now that
it is available nobody seems to care enough to actually make the code
work.
