 From that link it's clear that the OP means the plain meaning of 
these words, that on the failure path a bunch of unnecessary work 
should be skipped, rather than this very specific jargon reading. 
Jargon's just jargon and should be discarded rather than 
resurrected when it falls out of fashion or when it becomes a 
barrier to communication instead of an aid to it.

This idea was expressed better by Joe Armstrong anyway.
