It's not really sloppiness.  Python behaves the same way with its
contexts; both Python contexts and Dispose() are intended to be used
on objects that hold on to finite resources.  Similarly to Dispose(),
you can't reopen a closed NSStream.

IOW, Dispose() isn't a memory management technique, it's a
limited-resource-management technique.
