I would avoid bzip2 in favor of LZMA.  LZMA is a faster at compression
than bzip2, gets a better compression ratio in general, and is faster
at decompression.  See <http://tukaani.org/lzma/benchmarks>.

LZO is super fast, so maybe LZO could be used for on-the-fly
compression, and then a 'bzr pack' could be used later to do heavier
compression with LZMA, if desired, when the developer is not in the
middle of a task.

Colin
