	I see.

	The issue here is vray's "progress bar" information.

	Vray standalone is printing the progress output 'all on one line';
	vray thinks the output is going to a terminal when it's not,
	and is trying to do 'line overstrike' to show the progress
	all on the same line.

	Vray should really be doing an isatty() test on stdout to see if
	the output is going to a terminal, and if it is, use the technique
	it's using, and if it's not, use \n's between each line instead of \r's
	so that it ends up printing real lines of text instead of overstriking
	that can be viewed properly (consistently) in text editors.

	Try viewing that 1009 log file with different programs, and you'll
	likely see very different results in each due to this issue:

		cat /tmp/1009		-- shows only one line of output from vray
		more /tmp/1009		-- shows many lines
		vi /tmp/1009		-- shows one really long line (screenshot#1 attached)

	Each program views the data differently because the progress
	lines aren't real "lines"; it's /one long line/ of overstrikes.

	There's a setting in irush for displaying data like this;
	try turning OFF the Edit -> Preferences -> Use Tty Overstrike
	option, then view the log again.

	It should look like screenshot #2, which is probably what you want.

	Perhaps vray has a flag to control this progress output.

	But it really should do the isatty() test described above to detect
	this automatically.
