+TODO: treescan using extra fds
+        - IO::AIO did access uninitialised memory on unsuccessful stats.
+	- (libeio) added syncfs syscall wrapper.
+        - (libeio) set thread name on linux (ps -L/Hcx, top, gdb).
+        - (libeio) support multiple indepenent working directories.
+        - applied speling corrections by Nicholas Bamber.
+        - tune treescan #threads and #outstanding requests a bit.
+        - reduce the number of file descriptors in use at any one time
+          in treescan, to avoid running out of them (and using too much ram).
+        - take advantage of working directoriy abstractions
+          in aio_scandir and treescan.
+        - reduce compiled size by ~10% by not inlining some key functionality.

+	- INCOMPATIBLE CHANGE: fork is no longer supported (indeed, it never was),
+          see FORK BEHAVIOUR in manpage for details.
+	- passes testsuite on win32 now and may actually work
+          (activestate 5.10.1 / MSVC6, YMMV).
+	- (libeio) fix a deadlock where a wakeup signal could be missed when
+          a timeout occured at the same time.
 	- (libeio) added realpath.
+        - (libeio) added fallocate.
+	- (libeio) disabling sendfile on darwin unfortunately broke the emulation.
+        - (libeio) do not acquire any locks when forking.
+        - (libeio) use fewer time() syscalls when waiting for new requests.
