// Details: The MI Driver has a running state which is used to help determin
// which specific action(s) it should take or not allow.
// The driver when operational and not shutting down alternates
// between eDriverState_RunningNotDebugging and
// eDriverState_RunningDebugging. eDriverState_RunningNotDebugging
// is normally set when a breakpoint is hit or halted.
// eDriverState_RunningDebugging is normally set when "exec-continue"
// or "exec-run" is issued.
