** Revision 1.10  2010/11/12 06:06:43  gerlof
** Sometimes segmentation-fault on particular CPU-types
** due to memcpy i.s.o. memmove when moving memory in overlap.
**
** Revision 1.9  2010/10/23 14:04:20  gerlof
** Counters for total number of running and sleep threads (JC van Winkel).
**
** Revision 1.8  2010/05/18 19:20:02  gerlof
** Introduce CPU frequency and scaling (JC van Winkel).
**
** Revision 1.7  2010/04/23 08:16:58  gerlof
** Field 'avque' modified to 'avq' to be able to show higher values
** (especially on LVM-level).
**
** Revision 1.6  2010/03/04 10:53:37  gerlof
** Support I/O-statistics on logical volumes and MD devices.
**
** Revision 1.5  2009/12/17 11:59:36  gerlof
** Gather and display new counters: dirty cache and guest cpu usage.
**
** Revision 1.4  2009/12/17 08:53:03  gerlof
** If no coclors wanted, use bold display for critical resources.
**
** Revision 1.3  2009/12/17 07:33:05  gerlof
** Scale system-statistics properly when modifying window size (JC van Winkel).
**
** Revision 1.2  2009/12/10 11:56:08  gerlof
