// Thread plan used by single thread execution to issue timeout. This is useful
// to detect potential deadlock in single thread execution. The timeout measures
// the elapsed time from the last internal stop and gets reset by each internal
// stop to ensure we are accurately detecting execution not moving forward.
// This means this thread plan may be created/destroyed multiple times by the
// parent execution plan.
//
// When a timeout happens, the thread plan resolves the potential deadlock by
// issuing a thread specific async interrupt to enter stop state, then execution
// is resumed with all threads running to resolve the potential deadlock
