/**
* @author Philipp Haller
* @note This class inherits a public var called 'reactor' from ReactorTask,
* and also defines a constructor parameter which shadows it (which makes any
* changes to the underlying var invisible.) I can't figure out what's supposed
* to happen, so I renamed the constructor parameter to at least be less confusing.
