Or, as root on Linux with a fairly recent kernel:

echo 3 > /proc/sys/vm/drop_caches

real    0m0.053s
user    0m0.027s
sys     0m0.026s

not cached:
real    0m1.704s
user    0m0.033s
sys     0m0.066s

That's on an amd64 with reasonably fast disks; I could easily see it
taking much longer on another machine. As for the real-world behavior, I
would only be able to guess how often the requisite files are cached, so
I'm not going to argue either way.
