        Description

        Currently VirtualSpace always tries to use large pages when committing memory if large pages are enabled. Calls to VirtualSpace::expand_by may therefore cause it to commit more memory than intended. This can be problematic in low memory conditions where we want to limit the amount of memory that is committed.
