+/// UEFI Specification, Version 2.8, 4.4
+///
+/// As the boot_services table may grow with new UEFI versions, it is important to check hdr.header_size.
+///
+/// Boot Services must not be used after exitBootServices has been called. The only exception is
+/// getMemoryMap, which may be used after the first unsuccessful call to exitBootServices.
+/// After successfully calling exitBootServices, system_table.console_in_handle, system_table.con_in,
+/// system_table.console_out_handle, system_table.con_out, system_table.standard_error_handle,
+/// system_table.std_err, and system_table.boot_services should be set to null. After setting these
+/// attributes to null, system_table.hdr.crc32 must be recomputed. See UEFI Specification, Version 2.8, 7.4.
