Each thread just has a sequence of steps that is performed? Could you choose some strategic places within those steps to check to see if all is well? if(everythingOk) { DoSomething(); } if(everythingOk) { DoSomethingElse(); } // etc... Kind of cumbersome, but it's the only way I can think of offhand for terminating a loopless thread "naturally."
