 * Over-time loader. This pipeline can be attached to a non-ending observable, though, you can't rely
 * on the `finalize()` operator for checking if the loading is done or not.
 * The observables you supply into it should be completeable.
 *
 * This can be extremely useful when you want that each of the 'loader' start as soon as possible, but still keep
 * track of the progress. At the last `tap()` you can always see when one loader finishes that how many observables
