[CentOS] rsync to full disk

I recently noticed that an "rsync -av" to a full disk keeps sending 
files even after the target is out of space.  Has it always done that? 
I suppose it is reasonable to keep trying in case it subsequently 
crosses a mount point or space becomes available but I expected it to 
quit on that sort of error.
