+    * The generator is now better about not modifying the file list
+      during the transfer in order to avoid a copy-on-write memory
+      bifurcation (on systems where fork() uses shared memory).
+      Previously, rsync's shared memory would slowly become unshared,
+      resulting in real memory usage nearly doubling on the receiving
+      side by the end of the transfer.  Now, as long as permissions
+      are being preserved, the shared memory should remain that way
+      for the entire transfer.

     * Changed hardlink info and file_struct + strings to use
       allocation pools.  This reduces memory use for large
       filesets and permits freeing memory to the OS.  (J.W. Schultz)
