save instance state even when fail to spawn

Closes #41

Do you prefer ready or success? I feel like success is a better counterpart to fail.

Nbd though

I don't see this ready status as a counterpart to fail. I think the "counterpart" of ready is like killed or dead, maybe we could go with alive?
The fail is a state in the middle, perhaps fail is also bad naming.

I tried to draw a graph and ended up with this, I'll use new names for all status:

  graph TD;
      spawning-->alive;
      spawning-->broken;
      alive-->refreshing;
      alive-->killing;
      refreshing-->alive;
      refreshing-->broken;
      broken-->refreshing;
      broken-->killing;
      killing-->broken;
      killing-->dead;

Btw, I think I like these new names 🤔

Also I think we should eventually implement tracking of all these status.

Lgtm, but let's go with "faulty" instead of broken.
