Indeed, but I'm also on the lookout for lint-like tools (we already
have strict.lua built in, which helps, but static analysis would also
help; a truly exhaustive test suite + strict does have the same
effect, though).

No, it's a missing call to string.format. I've added this one and a
couple of others I found by grepping.

On the whole waitkey seems to me to work, and I'm at a loss to see
what could be going wrong at this particular site (unless you're
pressing a key!) so more help welcomed...
