I think Emacs does use threads (I don't know why).  I also encounterd this
when trying to make GDB asynchronous.  I think it was because I got to
ptrace (PTRACE_CONT,...) twice.  The second encounter (and maybe the first)
being

  if (ptrace (request, pid, 0, target_signal_to_host (signal)) == -1)
    perror_with_name (("ptrace"));

in i386_linux_resume where it failed.
