    A run configuration specifies how a target should be run, while a runner
    does the actual running.

    All RunControls and the target hold a shared pointer to the run
    configuration. That is, the lifetime of the run configuration might exceed
    the life of the target.
    The user might still have a RunControl running (or output tab of that RunControl open)
    and yet unloaded the target.

    Also, a run configuration might be already removed from the list of run
    configurations
    for a target, but still be runnable via the output tab.
