Richard and I played with this some. Basically a call like (C code):

  setvbuf( fp, NULL, _IONBF, 0 );

needs to be made on the file pointer immediately after the file is opened.
Now I do not know whether this should be wrapped up somehow, or simply
expose setvbuf through PHP. What is the preferred way of doing this?

Brian.
