The vast majority of changesets that are backed out from inbound are

Hopefully a push never burns all platforms because the developer tried
it locally first, but stranger things have happened! But what I'm most
interested in is whether patches are more likely to be backed out for
build or test failures. Perhaps if we could optimise our use of Try then
that would reduce the load on inbound. For example:

    * At first, the push is built on one fast and readily available
      platform (linux64 is often mentioned)
    * If this builds, then all platforms build
    * Only once all platforms have built are tests run

This would avoid running tests for pushes that are known not to build on
all platforms.


OTOH, it would significantly extend the time a developer has to wait before tryserver test results begin to appear. Which I think people would find discouraging.
