+/// As the system_table may grow with new UEFI versions, it is important to check hdr.header_size.
+///
+/// After successfully calling boot_services.exitBootServices, console_in_handle,
+/// con_in, console_out_handle, con_out, standard_error_handle, std_err, and
+/// boot_services should be set to null. After setting these attributes to null,
+/// hdr.crc32 must be recomputed. See UEFI Specification, Version 2.8, 7.4.
