Ah, I forgot this:

static void
i386_linux_new_thread (struct lwp_info *lp)
{
  struct arch_lwp_info *info = XCNEW (struct arch_lwp_info);

  info->debug_registers_changed = 1;

  lp->arch_private = info;
}

Hmm.  I'm starting to think that the easiest is jut to
go back at not calling new_thread for the first thread.
Let me give that a try.
