• note that the subBuilds key might be specific to the multijob plugin; I haven't tested this without it.
• we use this at Venmo to implement a fork/join style workflow -- the top-most build creates many parallel children, waits for them to finish, then collects their results (tests, coverage, etc) and merges them
