1. This should fix Issue 1625 (Bizarre Auto Frame Limit)

   Now the frame limiter yields on CPU thread, not as before on GPU thread mistakenly

2. Fixed clear of VI interrupts
   I guess VI interrupts are not used at all, because they were never cleared before

3. Made GPU thread 0% processor usage when paused whatever your active config is.
   I tried the event approach but somehow the thread resume latency is excessively long (Who can tell me why?)
