don't shot clean pages #130

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
If page is clean (no allocated objects, page is part of big unalloc space) we 
can safely skip it from being snapshotted - any previous snapshot data will do 
because no one will even access it except for allocator, and allocator accesses 
it write only - for dividing it into objects.

to do that allocator must inform paging about unused pages.
