Question: the ninja change will be done one builder by another?

[stgao, 2016/03/15 18:32:21]

No. The ninja change will be on recipe side on the waterfall bots. Once that is
done, we can deprecate this CL.
However, we need to wait for the next ninja release for that change to take
effect.

Since compiling the object files could speed up the culprit finding so much,
this CL will help a lot before the ninja release is available on the waterfall
bots.
