MP Build... FYI

[John Watlington]

Quanta wants assurance that the software workaround which was broken  
in #4479 is fixed.
Richard's testing is necessary to confirm this.   It is also  
essential that the kernel fix
which is theoretically the only difference between 624 and 625 be  
part of the production
test code to further confirm this.   If Quanta sees this problem AT  
ALL in the production
testing, there will be pressure to halt until further hardware/ 
software fixes are found.

But no, there is not need to rush testing to ship with fixed bits  
right away.  These machines
will be upgraded before anybody sees the problem in the field.
