I'll have a look at open() later and see if I can write a patch for python
3. I'm not sure its worth that amount of work for python 2 at this stage in
I'll also have a look at whether its possible to provide a safe alternative
to move and copyfile, even if it cannot be used on all systems. I'm not
thinking of actively hostile environments so much as multi-user situations.
