Just burned 3 days tracking down a Release only missing write barrier. Will be good to have this for shoring up the exact tracing work too. Really this should be called "find marked to unmarked pointers". Which would then have to manually be broken into the missing write barrier and false positive categories. We may even want to add an API to tell the GC a field of a certain object isn't a pointer to enable silencing of false positives.

Bug 604733 is a safety net for exact tracing. If we exactly trace all heap objects (ie no manual tracers or conservative default tracing) and use GCMember and friends everywhere (ie no manual write barriers) then the exact tracing safety net becomes a missing write barrier detector. That's nice.
