dtrace discuss - Feb 2007 - truncating aggregation output

Hi,

there was discussion on "truncating aggregation output only" 
(http://www.opensolaris.org/jive/thread.jspa?messageID=19008) on DTrace 
forum.
 From what was discussed the aggregation options like aggsortrev, 
aggsortkey, aggsortpos, aggsortkeypos are already available (Thanks Bryan!).

I am wondering what are current plans for ''aggtop'' option (or 
''truncating aggregation output'' functionality in general)?

thanks a lot,
