// This base class adapts both System V shared memory and "BSD"
// mmap to a common API.
//
// = DESCRIPTION
// This is a very simple-minded wrapper, i.e., it really is only
// useful for allocating large contiguous chunks of shared
// memory. For a much more sophisticated version, please check
// out the <ACE_Malloc> class.
