This will be fixed in upstream cwltool, I'll have to update when the fix is merged and released.

17072-update-cwltool @ 1cfcb49baf325386a409a1fe549dfb61e4982496

Update cwltool which fixes the original error (unbound variable 'result')

Also adjusts the default submit thread concurrency to 4.

I have a couple questions:

Do you think we could spare testing cwltool’s TaskQueue class, assuming it’s being tested there?
Changing nr of default threads from 1 to 4 may change the runner's RAM requirements, that seems to be 1 GB by default. Do you think this should also be adjusted?

The rest LGTM.

I forgot move the test over when I moved TaskQueue over. Will leave it for now but I'll move it over the cwltool in the future.

I don't think so. What the threads are doing is pretty lightweight, and the keep client object and collection cache (which are the biggest memory consumers) are shared among them.
