What you say is true, but then again, it's true of other things too. We're running in a completely virtual environment. Our "real" disk storage is EBS. Somewhere out on the network there's something which pretends to be a disk. Does "written" really mean "the bits have been committed to a piece of physical spinning iron oxide"? I have no clue. But, this conversation is getting very far away from Python. -- http://mail.python.org/mailman/listinfo/python-list
