I think what Richard's hazy memory is recalling is the time when
superpositions/junctions were predicted to able to somehow,
automatically, spread their work across all available processors.  While
 these kind of operations are inherently parallelisable, the perl
process that contains them is not (or at least is awfully less so).  So
if junctions are doing this, they will be using magic that is similar to
something from Sam's list.  I suspect that they aren't, though.
