In Dec 2005 Manmatha's group at U-Mass reported that the blob files in 010 have
problems. They in fact corrupt (not sure why, but it looks like we might of run
out of disk space when we were constructing them). 

I replaced them with the originals. Just in case we need to investigate this
further, the old ones still exist on our disks with the suffix "-BUGGY" but have
been removed from the distribution.
