Module breaks update.php's execution.

With this module installed I can't run update.php. I had to turn on errors to diagnose the problem but the short version is that;

update_prepare_d7_bootstrap( ) in update.php [Line #362] calls....
domain_variable_domain_bootstrap_full( ) which eventually calls ....
domain_api( ) which needs the function module_implements() from /includes/module.inc

The problem is that /includes/module.inc is not loaded in update.php until line #385...

*** If I hack domain.module to pull in module.inc, I then get a simular error message as Issue# 1559904***
Call to undefined function variable_realm_initialize() in
/folder/public_html/drupal-7.14/sites/all/modules/domain_variable/domain_variable.module

Is this issue the same as 1559904? Should we block execution the same way? (Check if 'update_check_requirements||update_prepare_d7_bootstrap' is defined???)
