// Details: Temporarily stall the process/application to give the programmer the
//          opportunity to attach a debugger. How to use: Put a break in the
//          programmer
//          where you want to visit, run the application then attach your
//          debugger to the
//          application. Hit the debugger's pause button and the debugger should
//          should
//          show this loop. Change the i variable value to break out of the loop
//          and
//          visit your break point.
