Add the initial dirty ring buffer test.
The current test implements the userspace dirty ring collection, by
only reaping the dirty ring when the ring is full.
So it's still running asynchronously like this:
I guess you meant "synchronously" here.
Thanks
vcpu main thread
1. vcpu dirties pages
2. vcpu gets dirty ring full
(userspace exit)
3. main thread waits until full
(so hardware buffers flushed)
4. main thread collects
5. main thread continues vcpu
6. vcpu continues, goes back to 1
