Hmm... I was hoping for an actual configurations and usage scenarios.
Preferably something people can set up and play with.  I take that the
CPU intensive helper threads are usually IO workers?  Is the scenario
where the VM is set up with a lot of IO devices and different ones may
consume large amount of CPU cycles at any given point?

Thanks.
