I'm not sure what gnu has to do with it, but you can seek to block boundaries. Unfortunately, the first step of the bzip2 algorithm is an RLE step, so that 900k block could have 46MB of input data in it, with the right values. At worst case, the 900k block would only have 720k of input data. The author says the RLE filter is a historical mistake.
If one had an index giving the uncompressed position at the start of each compressed block, then they could reasonably seek.
