-// Blocks of space for metadata are allocated out of Metachunks.

-// Metachunk are allocated out of MetadataVirtualspaces and once
-// allocated there is no explicit link between a Metachunk and
-// the MetadataVirtualspaces from which it was allocated.
-//
-// Each SpaceManager maintains a
-// list of the chunks it is using and the current chunk.  The current
-// chunk is the chunk from which allocations are done.  Space freed in
-// a chunk is placed on the free list of blocks (BlockFreelist) and
-// reused from there.

-// Future modification
-//
-// The Metachunk can conceivable be replaced by the Chunk in
-// allocation.hpp.  Note that the latter Chunk is the space for
-// allocation (allocations from the chunk are out of the space in
-// the Chunk after the header for the Chunk) where as Metachunks
-// point to space in a VirtualSpace.  To replace Metachunks with
-// Chunks, change Chunks so that they can be allocated out of a VirtualSpace.
