Raymond Buhr wrote a (very expensive!) book 'System Design with
Ada' (Prentice Hall 1984) notable for a complete diagrammatic
representation of Ada (83, of course) tasking which to my mind was
more complicated than the Ada language.

'professional'?

There are commercial tools as above, and there are open-source tools
(not sure whether Umbrello can do this, but ColdFrame
http://coldframe.sourceforge.net/coldframe/ certainly can).

In any case, tasking and state machines don't necessarily go and-in-
hand.
