	When using "-V sdl" I do indeed see "hardware YUV" in the video
	output window.

	Actually I'm in 24 bit mode (xdpyinfo output included below).

	Right, they are infrequent and do not appear to hurt anything.

	The Shm code does not appear to have the problem.

	Oh, I see you (or someone) updated the src/interface/intf_eject.c.  
	Just one more minor mod needed (to get the O_NONBLOCK and O_RDONLY
	flags).   Moving 'fcntl.h' down to a "#ifdef HAVE_FCNTL_H" block
	worked for me
