---------------------------------------------------------------
Here is a screenshot of this enhancement in action. The main spike, in the
beginning, is a test to set up some load on the host to see if it was suspect
for steal time. Then I let the host idle for a period of time.
The recording in vsd mirrors what would be seen in the traditional linux
toolset vmstat and top.

>
> In virtualized deployments of Geode some latency issues can be mapped back to
> the hypervisor not giving the guest enough cycles. For this improvement,
> Geode will capture stolen time as presented by the OS in the /proc/stat file
> for Linux. Steal time represents the time the virtual processor is waiting
> to be scheduled on the physical processor.
> Geode already monitors several CPU fields and Geode will be adding in support
> to capture STEAL time.
