That would introduce other failure modes:

1) User would require disk space for two complete copies of the
document.  So in the marginal case a user might load a document,
change just a character and then be unable to save.

2) Some file systems handle modify and create permissions separately.
So you could have the ability to modify a document, but not create a
new (temporary) one.

There are certainly cases where such an approach could help.  But it
is tricky when dealing with the exceptions.

The other thing to watch for is that some users cannot find their
files after saving, even if there is no problem with the saving.  They
forget the same, what folder they used, etc.
