Open the file in read-only mode or close it appropriately and all will
be well. The way you open it makes it read-write and by default files
you request write access to, cannot be opened again in write mode.
Therefore, if you change the first line to say:
FileStream readOnlyFileNamed: '...'
everything should be all right.
