When a human moves a stapler from one drawer to another, he has no

real 'gotcha' or trap that one could very easily fall into.

Oh, come on. That's a specious example. In fact, the situation here is
more like the person taking the staples _out_ of the stapler and putting
them in another stapler, and then being surprised to find that somebody
else put staples into the original.

There's no possible way for OO or _any_ other program to know what somebody
has done with a file outside that program, and that's as true in Windows as
Linux (and even though Word would lock the file, it _is_ possible to open
it with other Windows applications). The best an application can do is
compare the original file (or a checksum of it) to the current file before
writing to it, and warn the user if it has been changed.

Any analogy that deals with more than one person is invalid. So far as
the user is concerned, he is the only person using the computer. How
many processes or programs are running is irrelevant to him.
