  Modified files:
    lib/libc/i386/gen    rfork_thread.S 
  Log:
  Fix some rather interesting bugs that managed to not turn up in various
  testing and real-life applications:
  1) If you returned from the thread function, you got a segv instead of
    calling _exit() with your return code.
  2) clean up some bogus stack management.  There was also an underflow
    on function return.
  3) when making syscalls, the kernel is expecting to have to leave space
    for the function's return address.  We need to duplicate this.  It was
    an accident that the rfork syscall actually worked here. :-/
