I was going to wait for #344 to get merged first, but since these PRs are relatively independent I'll just rebase these changes. |

Followup to #344
On embedded platforms, we have a very limited number of threads (i.e. just two on the rp2040). Therefore, we would like the main thread to run a worker, rather than just sitting idle while other threads run workers. This PR proposes the simplest way of doing so.
One alternate approach is to make a list of threads, and a function that runs them all at once (essentially separating out the fork/join logic). I think it would look cleaner, but would involve a significant amount of extra code to create a "thread list" type. Since this "thread list" type would only be used once, I'm not sure if its worth the tradeoff.
Open to any other approaches as well.
