The gloda code review at https://wiki.mozilla.org/User:Andrew_Sutherland/MailNews/GlobalDatabase needs to have each point either be addressed or be tracked as a bug in bugzilla. This blocks pref-ing gloda on by default because we want to make sure that there are no hidden blockers in the review comments. (Also, we want the review closed out...)
Those items which have not been propagated to bugs or marked as addressed are believed to be trivial. This bug should probably remain blocking until dmose completes his review and I verify those additions are not blocking. This bug should then remain open until all items are dealt with or propagated to bugs. (I expect to end up providing a patch on here for most of what remains on the page.)
dmose completed his review in March. I have just re-checked the contents of the page and do not believe there is anything that is remotely a blocker that does not already have a bug and has not already been blocker-evaluated. Per my previous comment, I am dropping the blocker status of this bug as there are no longer any unknown unknowns.
