/**
 * Note that starting with GDB 7.12, as long as a PTY is available, this process
 * is used instead of GDBBackendProcess. This is because the GDB CLI is handled
 * directly by GDB and the current class only needs to handle the life-cycle of
 * the GDB process.
 *
 * This class is therefore a representation of the GDB process that will be
 * added to the launch. This class is not the real GDB process but simply an
 * entry for the launch to handle user actions but no IO.
 *
 * This class extends {@link GDBBackendCLIProcess} to re-use its implementation
 * of the {@link Process} abstract methods, but disables all I/O and
 * local CLI handling.
