	As far as I know O_NONBLOCK/O_NDELAY on regular files only
	prevents blocking on mandatory locks. Atleast that's how I
	interpret Solaris's manual page, and my test program indicates
	so too. How can double-buffering be done without non-blocking
	I/O?

	However you are probably right, one thread per physical device
	is enough. Doubling thread count was just a guess.
