Subject: several problems with JtR + jumbo 9 and/or omp-des-7
1/ NT support for x64 in 1.7.6-jumbo9 does not work properly :
$ john -w:lmcracked -rules:nt -stdout | grep coin.CO2010
words: 96 time: 0:00:00:00 100.00% (ETA: Wed Dec 15 14:24:24 2010)

coin.CO2010
$ john -w:lmcracked -rules:nt ntdump

It seems that only passwords stored with set_key(xxx, 1-8) work. This
problem was reported to me from a friend using my variation of the
official tree, and I reproduced it with the official jumbo patch. This
was tested with gcc 4.4.3 and ICC.
2/ the nice value is only effective for the first thread with openmp,
but I'm sure this is already known ...
3/ I ran into random problems with ctrl-C + restore, where the .rec file
was flock'ed. This only happened with openmp enhanced ciphers.
I did not investigate any of these problems, so this is merely a bug
report with no proposed fix, and perhaps not much detail. I'll try to
investigate the NT problem when I will have more free time.
