 * Revision 1.7  1997/03/26  09:31:00  gfa
 * rewrote the heap allocator. produces 50% less overhead, is much faster,
 * fully checked/reliable and written in 3 pages source (1 less). all boils
 * down to a ridiculous 880 bytes of mips machine code :-)
 *
 * Revision 1.6  1997/03/22  14:29:43  conrad
 * locks replace msg for heap
 *

 * fixed hmAlloc
 *
 * Revision 1.4  1997/03/10  13:55:39  gfa
 * changes for HeapMemory made
