//! Memory policies that can be used for spaces.
/// This class defines and manages spaces. Each policy is an instance
/// of a space. A space is a region of virtual memory (contiguous or
/// discontigous) which is subject to the same memory management
/// regime. Multiple spaces (instances of this class or its
/// descendants) may have the same policy (eg there could be numerous
/// instances of CopySpace, each with different roles). Spaces are
/// defined in terms of a unique region of virtual memory, so no two
/// space instances ever share any virtual memory.<p>
/// In addition to tracking virtual memory use and the mapping to
/// policy, spaces also manage memory consumption (<i>used</i> virtual
/// memory).
