There used to be two ways to pass parameters to new tasks, depending upon the configuration: Either (1) argv[] as created as an array with each string strdup'ed. Or (1) argv[] array and strings were created on the stack before the new task was started. Now, there is only one way, way (1). Way (2) might be slightly more compact, but this is not worth carry the complexity of two different ways of doing the same thing.
