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.
