Yes, I've checked with Linux-2.2.18 and SunOS-2.4
On SunOS-2.6 (Solaris 6), the F_ASYNC flag for async I/O has
disapreared, it seems they only provide async I/O through special system
calls (aioread, aiowrite, and so on), but I'm not sure. (I've just read
a few man pages)

Well this kind of problem does matters since we already have an example
of a Linux binary (The JDK for LinuxPPC) that broke because NetBSD does
not implement it the same way Linux does.
