# Previously, container images were being cross-compiled with buildx which uses
# QEMU for non-native platforms, which has unfortunately had long-running
# issues running the Go compiler:
# * [golang/go#24656](https://github.com/golang/go/issues/24656)
# * [https://bugs.launchpad.net/qemu/+bug/1696773](https://bugs.launchpad.net/qemu/+bug/1696773)
#
# This issue can be circumvented by ensuring that the Go compiler does not run
# across multiple hardware threads by limiting the affinity. I haven't noticed
# it since moving to nix, but keeping this line handy regardless:
