It's loaded at _system_rebuild_module_data from core system module.
This is called by update_verify_update_archive at the core update
module, which implements hook_verify_update_archive.

hook_verify_update_archive is called from update_manager_archive_verify.

This method is called from:

a) update_manager_install_form_submit.
b) update_manager_batch_project_get, called by
update_manager_update_form_submit.

Those are called from
a) $module_path . '/install'
b) $module_path . '/update'

So you can see that they are read when you try to install or update a module.

PS: Of course, if any of those methods are called from non-core code,
they will trigger the read of the files section of the .info files.
P.e. drush_get_modules at drush calls system_rebuild_module_data
You can find references to system_rebuild_module_data in core at
help.module, field module... and in contrib files like coder or
features.


Hope this helps.
