Occasional StorageFile errors, needing an 'eraseAll'

Okay... I used the WebIDE to delete the new file and that didn't help either

>require("Storage").getFree();
=2686684
>require("Storage").open("fitclock.log",­"w").erase();
=undefined
>require("Storage").getFree();
=2686684
>require("Storage").compact();
=undefined
>require("Storage").getFree();
=2686684
> 

Next I'll try to set the file handle to null before deleting it.
