FFI to sprintf ? yuch.

Is your SMLNJ using lazy lists? :)

strictly speaking : no.

Try hmatrix or uvector.

uvector is _probably_ the long term answer even after I solve the double -> string problem.

However, I would like to reiterate that it's the double -> string which is really the time/memory sink.  I verified this by printing a simple string based on the value (to make sure the value was evaluated) and it runs fast enough for me.
