It looks to me that this maybe was addressed in revs 1.49-1.51 of ffs_softdep.c. The authors (peter, kirk) can confirm/deny. I run softdeps on a lot of filesystem- most with not *that* heavy load, but at least one make world a day. The PR you report should in fact cause a failure under that. I think it's been fixed.
