Description
Currently if smartgroupcache time out is 0 then CiviCRM performs a TRUNCATE. Since 4.6 CiviMail has relied on transactions to do rollbacks and truncate breaks these. This means that setting smart group cache timeout to 0 causes CiviMails to go out when during the editing phase.
Note that on sites with many groups the smart group cache seems to detract from performance so it's important to be able to turn it off.
