[gambit-list] Post: Compare the productivity of computer languages

Uh oh. I created somewhat extensive SQLite3 bindings for Gambit for my
own use many months ago - I rewrote a Java program of mine in Gambit -
but the process of making them available to others got stalled back
then. I have been doing other, completely unrelated things, meaning to
return to that program some day...

Now my bindings would also need testing with the newer Gambit version.

Marc asked me if it was thread-safe. I replied that I don't know. I
still don't know.

It'll be a week before I can even think of opening that project.
