+ * an array of segment descriptors.  The first element of this array
+ * is a map structure, describing the arrays extent and the name
+ * of the controlled object.  Each additional structure represents
+ * a free segment of the address space.
+ *
+ * A call to rminit initializes a resource map and may also be used
+ * to free some address space for the map.  Subsequent calls to rmalloc
+ * and rmfree allocate and free space in the resource map.  If the resource
+ * map becomes too fragmented to be described in the available space,
+ * then some of the resource is discarded.  This may lead to critical
+ * shortages, but is better than not checking (as the previous versions
+ * of these routines did) or giving up and calling panic().  The routines
+ * could use linked lists and call a memory allocator when they run
+ * out of space, but that would not solve the out of space problem when
+ * called at interrupt time.
+ *
+ * N.B.: The address 0 in the resource address space is not available
+ * as it is used internally by the resource map routines.
