   After git clone bzr:: the size of the pack file will be about 12G (no
   delta compression), after git gc --aggressive it shrinks to 193K.

OK, i scrounged up a 15GB USB (1.0?!) external drive and was able to do
the "git clone bzr::" in 7.5 hours -- woo hoo!  It's somewhat tight now:

 $ LANG=C df -h .
 Filesystem      Size  Used Avail Use% Mounted on
 /dev/sdb1        14G   13G  794M  95% /mnt/mulo

This was after two failing attempts, both ending with an error message:

 bzrlib.errors.GhostRevisionsHaveNoRevno: Could not determine revno for
   {ID-1} because its ancestry shows a ghost at {ID-2}
 Write failed: Broken pipe

In both attempts, ID-1 was:

 kenner@gnu.org-19980613195110-2j7ddnyudwfyfytc

ID-2 for the attempts were (respectively):

 dmoncayo@gmail.com-20131207130209-d61sb5r2xuww52j0
 jan.h.d@swipnet.se-20131207142629-caazt8axffdl8p2o

On the third (successful) attempt, the only strange output was
(excerpt):

 progress revision 60600 'master' (60600/115406)
 progress revision 60700 'master' (60700/115406)
 Write failed: Broken pipe
 progress revision 60800 'master' (60800/115406)
 progress revision 60900 'master' (60900/115406)

I hope these errors are not an indication of tampering or corruption.
Next step is to snapshot this tree (somehow) and then do some local
munging experiments, perhaps starting w/ "git gc --aggressive".
