0000962: Limit the maximal internal block size to prevent memory exhausting through expansion at decompression
Currently FLAM works block by block. If you read a block with 64 KiB (default) a maximal expansion of GZIP by factor 900 can result in 1 GiB memory allocation by FLAM to handle the extracted block in memory. For a secure production environment the maximal allocated memory must be limited. In such case we need a solution, where only a part of the original block is extracted so that anything fit in the maximal block size. The default could by at factor 4 of the given block size.
