Enum NotBegun 

pub enum NotBegun {
    Crashed,
    Stalled,
    NotAProcess,
}

Why an operation never reached the process it was given to.

Carried rather than flattened away, because the next thing built on this has to tell these apart: an operation refused by a stall certainly did not happen, where one lost to a crash may have been half-done by the incarnation that died.

Variants

Crashed

The process had crashed and not restarted. Its volatile state went with it.

Stalled

The process was stalled. A command is a call from the layer above, on that process, so a stalled process’s layer above is stalled with it — there was nothing to make the call.

NotAProcess

There is no such process in this run.
