I understand everything you did except adding the guppi_seq.  Is there
any documentation regarding the semantics of seq?  I can see from
continuations.h it's the dynamic-root identifier, but is there any
significance to the choice of 100000, or are you just picking
something that's unlikely to ever clash with normal dynamic roots?

Thanks
