@denrase are we adding extensions to Isolate.spawn on this PR as well?

[denrase]

@marandaneto I will try to come up with something. Since there are no static extensions, we might introduce some additional helper so users don't have to do the spawn paused, add observer, resume isolate dance boilerplate.

Left a few comments but overall pretty good.
@denrase thanks.
