terminating child TCB. Or does RTM itself serialize the ETXR code so that a second instance is not driven until the first instance finishes (by exiting, thus going back to the parent's "main loop").
Unless the manual explicitly specifies that or how an exit is serialized, assume the worst - exit must be re-entrant and you are responsible for any needed serialization.
While it was a different set of exits, I was asked to diagnose an 0Cx of a commercial product on the market since the mid-seventies - two exits were invoked concurrently, and they used the same save area!
