 Is this caused by timed? That is, is it one of the time-related
 syscalls (which are not exercised that much) that's leaking nopreempt?
 
 Either way if you can figure out which syscall it's in when it dies,
 that'll make it a lot easier to trace what broke.
 
 (I know figuring this out is a pain; I was doing it yesterday with
 something else in userret)
