Hi,
hope it isn't too unexpected but it prints nothing for me neither in the
UP nor SMP case, just:

writing, page size = 4096

reading, page size = 4096
UP is a stable setup with 'FreeBSD 6.2-RELEASE-p1 i386' (32bit) and SMP a rather
adventurous setup with 'FreeBSD 7.0-CURRENT amd64' (64bit).
I ran the code for more than 10 minutes on each machine.
