Vicente,

I've created a very early experiment, here:

        https://gist.github.com/vprus/3a7bea25e4c0a0e4222d

Does it look generally right for you? I'm worried that Executor interface requires methods like
close/closed, try_executing_once and reschedule_until that don't seem documented in detail. Is
it fine to leave them undocumented in my case?
