> The usage of scratch file buffers in COSStreams is quite sloppy. A never filled buffer is created in the beginning and existing buffers are discarded without being closed when a variant of {{createOutputStream}} is called. Furthermore it should be clarified if requesting an input stream without having created an output stream before is ok and if a returned input stream keeps valid after a new output stream is created (which is crucial for proper buffer-closing). 
> This issue should resolve some of the shortcomings and document the expected or even required usage of COSStream.
