Things that still need attention:

   *    Make implementation changes necessary to allow multiple processes

        to use the mmalloc managed region simultaneously.  This requires,

        at the minimum, some sort of cooperative locking that ensures that

        only one process at a time is changing any of the mmalloc managed

        data structures (its ok for the mmalloc managed data regions to be

        changed at any time since we don't care about their contents).

   *    In order to support multiple processes using the mmalloc managed

        region, the malloc descriptor needs to be broken into two parts,

        one part which is specific to the given process and is maintained

        separately on a per process basis, and another part which is common

        to all processes.  As an example, the file descriptor is specific

        to a given process, as are the morecore and abortfunc pointers.

        However magic[], the version number, the flags field, etc are

        common to all processes.
