To give you an idea, right now there's 5 (5pm MTV time)pending builds and 4
slaves connected. Each build is ~15 minutes so it's still fine, the last build
will have a ~30 minutes wait time, so a 45 minutes try to results delay.

-  # will help us avoid doing so.  For example, we are starting off with

-  # If any file matches something compiled on the main waterfall
-  # android builder, use the android try server.
