Because the problem isn’t that there is one bug in a specific implementation, it’s that the whole model is fundamentally prone to this type of problem.

cgroups, Jails, and Zones all suffer from having to cover an immense surface area. Contrast with VMs, which only require managing a few, significantly simpler interfaces. There are definitely differences in quality, but they all use a similar approach.

OP says that fadvise is going to bottleneck in the same places on BSD that it does under Linux, with no supporting evidence. I agree that containers in general are a tough problem.
