Oh, sorry, that would have been helpful: Slackware64-14.0 Linux 3.2.45 #2 SMP Fri May 31 20:14:55 CDT 2013 x86_64 Intel(R) Xeon(R) CPU X5550 @ 2.67GHz GenuineIntel GNU/Linux glibc-2.15 I dug around in the kernel source looking for what exactly causes the counter to increment, but it wasn't at all obvious what was going on.
