  Log:
  Implement robust futexes. Most of the code is modelled after
  what Linux does. This is because robust futexes are mostly
  userspace thing which we cannot alter. Two syscalls maintain
  pointer to userspace list and when process exits a routine
  walks this list waking up processes sleeping on futexes
  from that list.
