kernel.test.ts

/*
I'm a little hesistant about testing this since we'll need to make sure that a kernel is
installed, e.g., to test on Github actions.
Probably, the way to go would be to install https://www.npmjs.com/package/ijavascript
and just test that a lot, since it would be the minimal dependency.

There are a lot of ideas for tests in this bitrotted place:
