by implementing some code that was missing so far ;) as well as
finding some real bugs. I also did some general cleanup, removing
debug strings and such. This code should be fairly OK to use, except
when "exec only when previous action was suspended" is used -- this is
NOT yet re-implemented in the tuned engine.
