Evgeniy Stepanov e109ef854a Release memory to OS only when the requested range covers the entire page 
Summary:
The current code was sometimes attempting to release huge chunks of
memory due to undesired RoundUp/RoundDown interaction when the requested
range is fully contained within one memory page.
