MP Build... FYI

[Mary Lou Jepsen]

We are also testing the first 1500 units for on rapid cycle
suspend/resume.  If the 625 build fixes this - it would be excellent to
get the most data we can on our best solution.

However, richard pointed out a back up - we can take the units that fail
the 24 hour test and put 625 on them and then run them for another 24
hours.

I'm about to meet with richard, matt, gary and arnold now.
