	I've been tracking down a problem we've had lately where jobs are failing, 
and I have a quick question.  If multiple jobs running on the grid were to 
attempt to simultaneously write to the *same* .o file - is that something 
that SGE handles gracefully, or could it lead to trouble?  We've never had 
trouble with this before, but since increasing the number and speed of the 
systems online, I'm wondering if it's triggered a heretofore hidden problem.

	Thanks for any thoughts,
