[platform-releng-dev] Updated "plan" for Mars.2 RC2 and Neon M5 builds

["David M Williams" <david_williams@xxxxxxxxxx>]

Team, 

Due to the issues described in bug 486804
[1] we are going to do another build, with EMF pre-reqs reverted. I'll
schedule the Mars one for 2 PM (Eastern) and the Neon one for 4 PM (Eastern).
The builds will be complete in 2 or 3 hours after they start, but unit
tests will take another 6 to 12 hours to be complete. 

The issue is still be investigated,
but as of now, we do not know if it is a regression in EMF, or a "test-only"
problem. And, in the worst case, even if our tests were making some incorrect
assumption related to 'order' or iteraters, we might be making the same
incorrect assumption in our code?

The goal is that by the time that build
is ready (or before :) we will understand the root problem completely.
But by having another build "in the wings", we will be in a position
to provide one or the other. The current candidate, if it does turn out
to be a "test only" problem. Or, the new one, if it is an EMF
problem and EMF decides to revert their current fix. 

So, as usual, leave the tip to each
branch untouched until we announce! 

Thanks,
