Unfortunately I couldn't figure out how to get gnuplot to do this. I ended up
doing it in gnumeric. I'll look into fixing it the script up to be more
automatic. Maybe look at gnuplot again.

Heikki suggested some things to test for regressions. I'll look at that.
What I'm more curious about and hoped I could get data from others is whether
posix_fadvise(WILL_NEED) does anything useful on various versions of FreeBSD,
OSX, etc. Afaict the syscall doesn't exist at all on Solaris though, which
surprises me :(
