Not necessarily only in embedded systems, the use of simplest threads to implement error handling (a.k.a. "vulture threads") can greatly simplify the complexity. Descendants of this 'Thoth' system were "Waterloo Port" and the early versions of "QNX" (where embedded systems come into play again). When interested in details, you're welcome to contact me.
