lots of noise, but is good for finding bugs like "warning: comparison
between signed and unsigned".

+CPU load
+--------
+
+Linux exports various bits of information via `/proc/stat' and
+`/proc/uptime' that userland tools, such as top(1), use to calculate
+the average time system spent in a particular state, for example:
+
+ $ iostat
+ Linux 2.6.18.3-exp (linmac) 02/20/2007
+
+ avg-cpu: %user %nice %system %iowait %steal %idle
+ 10.01 0.00 2.92 5.44 0.00 81.63
+
+ ...
+
+Here the system thinks that over the default sampling period the
+system spent 10.01% of the time doing work in user space, 2.92% in the
+kernel, and was overall 81.63% of the time idle.
+
+In most cases the `/proc/stat' information reflects the reality quite
+closely, however due to the nature of how/when the kernel collects
+this data sometimes it can not be trusted at all.
+
+So how is this information collected? Whenever timer interrupt is
+signalled the kernel looks what kind of task was running at this
+moment and increments the counter that corresponds to this tasks
+kind/state. The problem with this is that the system could have
+switched between various states multiple times between two timer
+interrupts yet the counter is incremented only for the last state.
+
+
+Example
+-------
+
+If we imagine the system with one task that periodically burns cycles
+in the following manner:
+
+ time line between two timer interrupts
+|--------------------------------------|
+ ^ ^
+ |_ something begins working |
+ |_ something goes to sleep
+ (only to be awaken quite soon)
+
+In the above situation the system will be 0% loaded according to the
+`/proc/stat' (since the timer interrupt will always happen when the
+system is executing the idle handler), but in reality the load is
+closer to 99%.
+
+One can imagine many more situations where this behavior of the kernel
+will lead to quite erratic information inside `/proc/stat'.
