There was a problem hiding this comment.
Note: This will help reduce the potential for occurrence, but does not eliminate it as the Dispose call could be taking place as the timer callback is invoked.
The focus of these changes is to address a race condition that could cause the authorization refresh timer callback to throw an ObjectDisposedException due to a set of benign race conditions. These changes attempt to make those conditions less likely but cannot elimitate them completely without introducing synchronization overhead. Because the condition is benign, accept the resulting exception as an expected case rather than paying that cost.
