If I may suggest an alternative? It is generally not nice to kill tasks
forcibly on the Amiga. It leads to all sorts of race conditions, vis-a-vis
freeing resources, stopping I/O, etc. A much cleaner solution is to give
your task a message port that it monitors. When you want it to die, send
it a kill message. It would then clean up and reply. After the reply you
could RemTask(), it.
