Just to clarify...  Is it really the window scaling?

My hit is that window scaling is fine.  Just set the default to
something big.  The problem with the current approach is that
turning on window scaling means you need to turn on timestamps
immediatly.  I would rather turn on timestamps (or another such
mechanism) when we need them for PAWS.  

Would you have window scaling itself be enabled in the middle of a
connection?  I see that as ugly, I think.
