Hi Dave & Michael,

I am working on Dave's new bitmap schema, I have finished the part of getting the 'hybrid scheme bitmap'
and found the complexity was more than I expected.  The main issue is more memory is required to
 save the 'hybrid scheme bitmap' beside that used to save the raw page bitmap, for the worst case, the
memory required is 3 times than that in the previous implementation. 

I am wondering if I should continue, as an alternative solution, how about using PFNs array when
inflating/deflating only a few pages? Things will be much more simple.


Thanks!
Liang
