Comment 1 for bug 820525

Hmmm, based on Yavor's contribution list in pbzip2.cpp version 1.1.5 it sounds like this is already implemented:

"Signalling error on stdin decompression when file doesn't start with correct bzip2 magic header"

"Handle decompression of very long bz2 streams incrementally instead of loading whole streams in memory at once"

I'll poke around and see if I can figure it out, but maybe some more documentation is called for. Thanks!
