I tried this on two uniprocessor x86 machines:

(1)

$ uname -a
Linux tokyo 2.6.0-test10 #3 Mon Nov 24 13:43:54 EST 2003 i686 GNU/Linux

This machine produces this output, after running the test app for
about 30 minutes:

out of order tv_sec: 1070067959 929846, prev 1070067957 813066
out of order tv_usec: 1070068017 80145, prev 1070068017 80384
out of order tv_usec: 1070068017 104138, prev 1070068017 104368

(2)

$ uname -a
FreeBSD home.samurai.com 4.9-RELEASE FreeBSD 4.9-RELEASE #0: Thu Nov  6 21:25:41 EST 2003
bryanf@joe.samurai.com:/usr/obj/usr/src/sys/SAMURAI i386
 

This machine produces no output after running the test app for about
30 minutes.
