    // Handle an unhandled error in the main thread

    // Note that 'uncaughtException' is a crude mechanism for exception handling intended to
    // be used only as a last resort. The event should not be used as an equivalent to
    // "On Error Resume Next". Unhandled exceptions inherently mean that an application is in
    // an undefined state. Attempting to resume application code without properly recovering
    // from the exception can cause additional unforeseen and unpredictable issues.
    //
    // Attempting to resume normally after an uncaught exception can be similar to pulling out
    // of the power cord when upgrading a computer -- nine out of ten times nothing happens -
    // but the 10th time, the system becomes corrupted.
    //
    // The correct use of 'uncaughtException' is to perform synchronous cleanup of allocated
    // resources (e.g. file descriptors, handles, etc) before shutting down the process. It is
    // not safe to resume normal operation after 'uncaughtException'.
