I wonder how it would change the semantics of the store? I think the current failure caching system is only based on the hash of the dependency graph. Is that correct? That reinforces the determinism of the system. It seems impossible to make build hook and timeout failures deterministic. Both depend on things that can't be observed by the daemon or the builder. So if these failures are cached, the caching should be enabled separately from the memoized failures. I think that if we do decide to cache timeout failures, the value of "--timeout" and "--max-silent-time" should be included. I have a slow machine that can't build certain packages with the default "--max-silent-time" even when nothing is "competing" for the system's resources. But of course there are other factors that affect this like other processes on the system so it's not deterministic. > Patch compiles, but is yet untested since the system I need it has gone away > for the time being..
