# Pin resources and disable the VPA. This job compiles every native
# extension in parallel (CMAKE_BUILD_PARALLEL_LEVEL=12, set above) whenever
# the ext_cache is cold (e.g. a newly added Python version), which peaks
# well above the ~5Gi the VPA otherwise tunes it down to and gets OOMKilled.
# Matches the resource requests used by the native package build jobs.
