+// A very simple allocator class which allows allocation, but not deallocation.
+// The allocations can be made read-only with the Protect() method.
+// This class is NOT useful as a general-purpose memory allocation system,
+// since it does not allow deallocation.  It is useful to use for a group
+// of allocations which are created in the same time-frame and destroyed
+// in the same time-frame.  It is useful for making allocations of memory
+// which will not need to change often once initialized.  This memory can then
+// be protected from memory smashers by calling the Protect() method.
