Display image in second thread, OpenCV?

Question

I have a loop to take in images from a high speed framegrabbger at 250fps.

/** Loop processes 250 video frames per second **/
while(1){
  AcquireFrame();
  DoPr

Ok. So embarrassingly my question is also its own answer.

Using CreateThread(), CvShowImage() and CvWaitKey() as described in my question actually works-- contrary to some postings on the web which suggest otherwise.

In any event, I implemented something like this:

/** Global Variables **/
bool DispThreadHasFinished;
bool MainThreadHasFinished;
iplImage* myImg;

/** Main Loop that loops at >100fps **/
main() {
  DispThreadHasFinished = FALSE;
  MainThreadHasFinished = FALSE;
  CreateThread(..,..,Thread,..);

  while( IsTheUserDone() ) {
    myImg=AcquireFrame();
    DoProcessing();
    TakeAction();
  }
  MainThreadHasFinished = TRUE;

  while ( !DisplayThreadHasFinished ) {
     CvWaitKey(100);
  }

  return;
}

/** Thread that displays image at ~30fps **/
Thread() {
  while ( !MainThreadHasFinished ) {
    cvShowImage(myImg);
    cvWaitKey(30);
  }
DispThreadHasFinished=TRUE;
return;
}

When I originally posted this question, my code was failing for unrelated reasons. I hope this helps!
