Maciej mentioned on IRC that it was surprising that the process ever got into this state.
It happened on a system that was crawling due to massive paging, possibly after a web process crash. I speculate that it was a race condition related to exiting / crashing.
Sam said on IRC that this should be an ASSERT and not a null check, since we should not get into this state.
