Can you explain why? We have a thread that has detected that it's spinning. Keeping on spinning is a waste of cpu time. Why not let something else use the cpu?

Because its a polling interface. I much prefer it if we were to get a
wakeup notification when the vcpu holding the lock releases it.

It's a fully virtualized guest. There's no way to get this without patching the guest kernel.
