Innodb speed improvement building group cache (autocommit=0)

As seen here:
https://dev.mysql.com/doc/refman/5.5/en/optimizing-innodb-bulk-data-loading.html

There is a quick fix for improving the speed of bulk insert statements (when using mysql/innodb).

SET autocommit=0;
... SQL import statements ...
COMMIT;

In our tests, wrapping this around the insert statements for loading contacts into groups reduces the time it takes to rebuild a ~300'000 contact smart group by about half.

CRM_Contact_BAO_GroupContactCache.php ~Line 53

CRM_Core_DAO::executeQuery("SET autocommit=0");
CRM_Core_DAO::executeQuery(
        "INSERT IGNORE INTO civicrm_group_contact_cache (contact_id, group_id) SELECT DISTINCT $idName, group_id FROM $tempTable");
CRM_Core_DAO::executeQuery("COMMIT");

This approach could be used for other areas large inserts are performed?
