+File list structure in memory

+  Rather than one big array, perhaps have a tree in memory mirroring
+  the directory tree.  
+
+  This might make sorting much faster!  (I'm not sure it's a big CPU

+  It might also reduce memory use in storing repeated directory names

+  Advantages:

+    - will automatically be up to date with bugfixes in zlib

+    - can leave it out for small rsync on e.g. recovery disks

+    - can use a shared library

+
+  Should we ship zlib for systems that don't have it, or require

+  Apparently this will make us incompatible with versions of rsync

+  do this is to just disable gzip (with a warning) when talking to old
