  Log:
  rfork(2) wrapper for simple rfork-style threads.  I have lost count of
  the number of times I have given this to people and got asked: why isn't
  it in libc?  It is impossible to do this without assembler glue to reset
  the stack for the new child process.
  
  int rfork_thread(flags, stack_addr, start_fnc, start_arg)
  int flags;                 Flags to rfork system call.  See rfork(2).
  void *stack_addr;          Top of stack for thread.
  int (*start_fnc)(void *);  Address of thread function to call in child.
  void *start_arg;           Argument to pass to the thread function in child.
  
  This is deliberately not documented or prototyped in includes until the
  corresponding alpha version is written.
