Hi Wei,

I'd like to share some of my experience with the improved RTDS scheduler.
It is not a formal report. But hopefully it is some useful information.

I have been using the improved RTDS in the staging for a while. I
haven't seen any weird issue. Because I also modify the other parts of
Xen a bit, so the test is not for xen 4.7-rc2 though. That's why we
have Chong test the xen 4.7-rc2. Thank you very much, Chong, for your
nice test report! :-)

The workload types I run are:
1) Compile linux or xen kernels in parallel. The number of compiling
jobs is usually double the number of cores allocated for dom0.
2) Run cpu-intensive task or memory-intensive task,which access a large array.
