 TODO: aio_fcntl, at least for file-locking
 
+	- speed up readdirx sort algorithm slightly.
+

+	- new options --dirs and --files for treescan.
+        - install bin/treescan by default.
+        - (libeio) aio_readdir can now be cancelled while executing.
+        - fix a printf format string for 64 bit systems (could lead
+          to problems on big endian 64 bit systems).
+        - do not use qsort() but our own algorithm: glibc initialises
+          the whole locale and I/O subsystem inside qsort, causing
+          a stack overflow on 32 bit machines. The new sort uses much less
+          stack and is more than twice as fast in typical situations.

 	- (libeio) pwrite emulation was even more flawed than intended and did
           not restore the file offset.
+        - add aio_readdirx, which can return inode and filetype and sort
+          the names in various ways.
         - unfortunately, utime, chmod, chown on an open file that has just
           been written can easily block, which caused aio_copy to block the
           process. no more!
