---------------------------------------------------------
I worked on this a bit, adding a {{seek(byte_offset)}} and {{get_block()}}
method to the _CompressedFile class (see
[commit|https://github.com/tim1357/incubator-beam/commit/2eb536d519f23d2ab9a402482420ff70b7c3de4e]).

> Make BZIP compressed files splittable

> Bzip2 is compressed as blocks, so it should be possible to do dynamic
> splitting. To do this: Seek to a location in the bzip, then keep seeking
> until you find the 6 byte block-start sequence 0x314159265359 (which is the
> 12 digit approximation of pi). You can use a bzip2 decompressor from that
> point onwards.
