  Unfortunatly, your "fix" is wrong and the original was right. I quote
  from the manual:
  
       If timeout is a non-zero pointer,  it  specifies  a  maximum
       interval  to wait for the selection to complete.  If timeout
       is a zero  pointer,  the  select  blocks  indefinitely.   To
       affect  a  poll,  the  timeout  argument should be non-zero,
       pointing to a zero valued timeval structure.
  
  So the correct value for the "timeout" parameter was the original zero
  pointer.  Also, you forgot the "exceptfds" parameter and to put the
  "timeout" in a pass-by-reference "timeval" structure.  Please post a
  correction to unix-emacs.

-----------------

Well, my man page didn't read that way; a little poking around here 
uncovered for me a 4.1c man page which does read that way. We're
running 4.1a here, so if that's your flavor too then use the fix I
had posted, else use the fix to the fix (i.e. use the original text).

Looking forward to when the powers that be here get us 4.1c ...
