We have been down this road before. Virtually all people
who do production work with beowulfs are not interested in
OC'ing issues. Furthermore, when you use something out of spec, 
there is no way to know if "your out of spec behavior" is the 
same as "my out of spec behavior" and therefore it makes no sense
discussing these issues in a forum where stability and reproducibility
are important. I am sure there are other
mailing lists that deal specifically with these issues.
