I would organize tasks as trees, at least thats the way I have
implemented them by now. This allows eg. to kill parent tasks if one of
the childs fail. The present task API is IMHO quite incomplete and needs
some rework, but I did not want to bring this up for the current
version. This is certainly a topic, that should be considered for the
next API version.
