After deploying a version of gvisor built with Go 1.14, we're seeing errors setting up cgroups (we manually run `runsc` via `runsc run`, which creates the cgroup). This turns out to be a known issue with Go: golang/go#38033. Given that the [fix won't be backported](golang/go#39026 (comment)), we should retry writes that may fail with EINTR. This is also what runc does: opencontainers/runc#2258 FUTURE_COPYBARA_INTEGRATE_REVIEW=#3102 from stripe:andrew/cgroup-eintr 079123b PiperOrigin-RevId: 320183771
