Well, freezing the TSC while a guest is descheduled is not very nice at all, but I can imagine it stops you getting time went backwards messages if you are also forcibly re-setting the TSC on PIT ticks. :-)

I think freezing the TSC is probably a very bad idea for guests. I really do want to know what's going on.

In summary, I'm not sure about this patch. I feel that if I take it I'm encouraging 'onward and upward' development without spending the time to make sure fundamental abstractions like time are designed and implemented soundly.

I think you should heed your intuition ... it's usually quite solid!
