/*
 * Demonstrates a conhost hang that occurs when widening the console buffer
 * while selection is in progress.  The problem affects the new Windows 10
 * console, not the "legacy" console mode that Windows 10 also includes.
 *
 * First tested with:
 *  - Windows 10.0.10240
 *  - conhost.exe version 10.0.10240.16384
 *  - ConhostV1.dll version 10.0.10240.16384
 *  - ConhostV2.dll version 10.0.10240.16391

    // sufficient.)

    // The same hang occurs whether line resizing is off or on.  It happens
    // with both "Mark" and "Select All".  Calling setBufferSize with the
