I managed the extract that file successfully.
   I uploaded the extract to GitHub if you wanna just git clone it
   instead:

     Seems legit except 'extract' has been chewing on the file for 45
     minutes
     now without spitting out any useful bits that I can see, while 'top'
     indicates 99% of CPU cycles dedicated to the task.  It's kind of
     reassuring that 'extract' reports files in "GNU tar format" were
     found.
     But @126 MB I would expect /most/ archive files of this size to
     unpack
     in way less than a minute here.
     amidoinitrite?
     Has anybody got a verifiably useful copy?
     :o)
