[Haskell-cafe] How to move files?

Hi Josh,

the fastest and safest way is to create the temporary file in the
directory of the final location and then move the file to its final name.

This way you ensure that the temporary file is always on the same device
or partition as the final file and therefore a move is always possible.

And it's the safest, because a move is an atomic operation - which copy
isn't - and therefore other processes will never see a partially updated
