Hi Bill, what do you think of the following code?
(please overlook the pseudocode aspect, I'm not completely familiar yet with
the boost.thread syntax..)

Mutex mutex;
Condition cond;
DataObj sharedData;
bool serverRunning = true;

void* threadfunc(void*);

int main()
{
    Thread* t = new Thread(&threadfunc);
    while (serverRunning) {
       ...
       Lock lock(mutex);
       sharedData.ready = false;
       sharedData.question = ...;
       while (!sharedData.ready)
           cond.wait(lock);
       cout << "the answer is: " << sharedData.answer << endl;
       ...
   }
   thread_join(t);
}

void* threadfunc(void*)
{
  Lock lock(mutex);
  sharedData.answer = 42;
  sharedData.ready = true;
  if (random() % 2)
     throw catch_me_if_you_can();
  cond.signal();
  return 0;
}

thanks,
hys
