>
> Currently direct buffers allocated by compression codecs like Gzip (which 
> allocates 2 direct buffers per instance) are not deallocated when the stream 
> is closed. Eventually for long running processes which create a huge number 
> of files, these direct buffers are left hanging till a full gc, which may or 
> may not happen in a reasonable amount of time - especially if the process 
> does not use a whole lot of heap.
> Either these buffers should be pooled or they should be deallocated when the 
> stream is closed.
