On a side note, watching this thread, I'm a bit curious why everyone is
manually closing their files, why not...

    | memory |
    memory := Bitmap new: 6 * 1000 * 1000.
    memory atAllPut: SmallInteger maxVal.
    FileStream 
        newFileNamed: 'f.out' 
        do:[:f | f nextPutAll: memory asByteArray]

Why is everyone ignoring that every file open method has a corresponding
#do: that encapsulates the close and removes the need for a temp?
