Overcommit wasn't my main point. My point was that the intersection of systems where: - You are using the stdlib (so not designing an OS or other low level programming) - OOM must be recovered from - OOM-as-panic with recovery at a higher level in the application is not going to work and you need fine grained OOM recovery is small. Overcommit makes it smaller, but ignoring that it is still small.
