You did make me think about the interface a bit further.  If you were
going to ack one of the versions of this patch, which would you prefer? 
The previous version, this new version or something else?

The difference here is that we use a replaced function call vs using the
if statement.  There are more lines source in the kdb, but the interface
api is clean.

Thanks,
Jason.
