The only reservation I have is inexperience with lbzip2, and at least one
comparison I saw cited high memory requirements and out of memory crashes
with lbzip2. I will have to find the page when I'm back at a computer, and
it may very well have been addressed by now.

Not being updated in a while is not a bad sign for a tool you just want to
work.

The unzipping anything in parallel, however, is a distinct advantage, and
makes it worth examining.
