Is this actually correct? There were a bunch of workarounds and fixes
put into this code over time. Please check with Chris Lalancette, I
think he was the last to touch this code.
Once upon a time we injected PIT interrupts from the vcpu thread (even
though the PIT is external to any vcpu) which let to a lot of
complications in the implementation. This patch removes one of them.
