Goroutines are conceptually very similar to threads, but much lighter weight.
They are far cheaper than system threads to run. It's not uncommon for go apps

In Go, you can check if a type satisfies a particular behavior by declaring
an interface, and then checking if the type satisfies that interface.
In your case, you can check if the error is `Temporrary()` or not.
