The only work I've done on ht://Dig 4 is some database schema tests. The task
of a complete rewrite is big and unfortunately I do not have any spare time to
spend on this project.

I started that at one point but gave up after finding InstandDB... It is too
much work, considering there are already some good implementations out there.
InstantDB does well enough. It performs better than Cloudscape and seems to
have better support, runs faster, support more of the SQL92 standard and has a
*much* better licensing arrangement.
