I should amend this a bit. By 'benign' above, I meant that you
wouldn't lose the filesystem. But if trickle-sync is working too
slowly or not at all, I would think that, in the event of a crash
preceded by writes to a softdep-mounted filesystem, more data could be
lost than if trickle-sync were working as intended. Which wouldn't
feel so benign if it happened to you.
