It is currently conceptually depricated in kst in real time/read to end mode.  
Kst needs to know how many (complete) frames are available in a data source, 
in which it is assumed that all fields have the same size.  The concept of 
the virtual 'INDEX' field also sort of demands this.  This is the reason that 
I never brought in your getdata (you added the extra parameter, which I 
couldn't use).  It would take a pretty serious re-work of the data source 
model to change this, I think.

The point Don was making is that defile, the real time dirfile writer, needs 
to make sure that kst know how many frames are available in *all* of the 
fields, otherwise you get weird effects (eg, X field momentairily has more 
frames than Y).
