This is already checked for elsewhere in the code befor caling this
function. I suppose I should have mentioned this.

The idea of this function is to show the user how much free space there is
in a filesystem. If they click OK then this directory will be created
anway if it does not exist. Therefore it is quite useful for this function
also to check if the directory can be created.

Ohloh's site says they use COCOMO, which is known to be more accurate for
large mature projects and less so for small young projects:
