What is "catchup" and what is "gradual"?
Just placeholders to point out that there are different algorithms to replaying interrupts to a guest. I called what we implemented "catchup" since we pretty much immediately send all of the missed ticks to the guest in order to catch-up.
I'd imagine that a 'gradual' algorithm would shorten the tick interval until you've caught up. The Hyper-V paravirtualization manual has provisions for the guest to request what type of algorithm is used so it makes sense to accommodate this in our syntax.
