The bug described back in 2004 in the following message still seems to exist:
http://linux.derkeiler.com/Mailing-Lists/Kernel/2004-05/4313.html Essentially, it appears that if a process sleeps before it uses up a complete jiffy then no charge is made to its process accounting table. This problem still exists in the same manner in kernel: 2.6.15-1.2054_FC5smp #1 SMP Tue Mar 14 16:05:46 EST 2006 i686 i686 i386 GNU/Linux The linked message above contains the necessary code to easily test for the problem. It compiles cleanly, just be sure to include -lrt on the command line.
