How does it survive for 30s longer than the cutoff? All its DB work completes within the timeout, but then it sits forever spooling out emails to postfix - which for some as yet undiagnosed reason can be many ms per email. We haven't instrumented things well enough to get a handle on that yet, but we're also sending too many emails,and from an interactive context which is nuts.
