Parallel implementation of bzip2
PBZIP2 is a parallel implementation of the bzip2 block-sorting file
compressor that uses pthreads and achieves near-linear speedup on SMP
machines. The output of this version is fully compatible with bzip2
v1.0.2 or newer (ie: anything compressed with pbzip2 can be
decompressed with bzip2).

Changes in 1.1.1 (Apr 17, 2010)
- Modified decompression to use low-level libbz2 API to improve
performance of long bzip2 streams of large single-stream bzip2
- This release should now decompress files created with bzip2
at least as fast as bzip2 or slightly faster
- Handle decompression of long bzip2 streams incrementally
instead of loading whole stream in memory at once
- Fixed is
