    I found this pr, which seems to be a likely candidate.

    http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/55007

    dccm is threaded, but libmilter does not call kqueue directly, but
    based on other searches, I'm suspecting that various calls are
    implemented using kqueue, kevent (select(), poll(), etc..). I see
    some evidence of this in the sources, but I'm not familiar enough
    with the kernel code to say absolutely that these code paths are
    executed.
