Please excuse the subject line; when I was first writing up the e-mail, I thought the issue was caused by a bug with how delayed allocation when under memory pressure interacted with mballoc(). Subsequent tests showed my initial theory was incorrect, and I fixed the text of my e-mail, but not the subject line.... - Ted
