    How far into the run does this happen? Immediately, or after a while?

    Hm. I haven't touched Valgrind in a couple of years, and I suspect
    people haven't been as mean to it as I was being. It might be time I
    gave it some love. (I've also been thinking about porting it to be a
    Xen guest so that we can Valgrind whole virtual machines - but that's a
    different story.)
