I have tons of these in 6-STABLE, from normal ps/w/top usage, without 
the use of a debugger. CURRENT however seems to work fine for me, but it 
seems the changes are too great to MFC, so what i did is i just 
commented the warnings out from the source code.

Look into src/sys/kern/kern_resource.c, and comment out the following 
statement

---
               printf("calcru: runtime went backwards from %ju usec "
                    "to %ju usec for pid %d (%s)\n",
                    (uintmax_t)ruxp->rux_tu, (uintmax_t)tu,
                    p->p_pid, p->p_comm);
---

 recompile kernel.
