The primary requirements for adding a builder to the list of builders
for a given branch are:

 1. it must build the branch without errors so as avoid introducing
    unrelated build failures on unrelated patch submissions

 2. the builder must be fast enough to keep up with the other
    builders from a throughput perspective.

Adding multiple builders can increase overall throughput at the cost of
increased latency across all builders.   This is a result of the
increased network load resulting from multiple builders fetching the
repo in response to a build notification.

If multiple builders for the same platform are going to be added, it is
very important that the machines that are hosting them be identically
configured.  The opportunity for a patchset to pass or fail should not
be the result of which builder it randomly assigned to.
