Question

I would like to do something like the below for a multi-threaded program:

// wait for variable to become true but don't hog resources  
// then re-sync queues  

Is something like this a good solution?

while (!ready) {
    Thread.Sleep(250); // pause for 1/4 second;
};

No, this is not a good solution. First it might sleep too long. Second it’s easy for threads to get into lockstep. Here’s couple of links to MSDN articles on proper synchronization techniques:

• Conditional variables
• Events
