> How will expunge on shutdown factor in?  Is it likely to trigger compact?

And there it is, the complicating factor I haven't thought about.

Expunge on shutdown triggers a compaction of the inbox (and presumably we want this). The compaction does happen earlier in shutdown than the patch here would prevent, but I'm unclear if shutdown waits for it to finish before moving to the next phase. I did a simple test and it appears that compaction _was_ completed.

Either way, if it lasts for over a minute the shutdown terminator will kill it and we'll continue to get the crash reports this bug was trying to prevent.
