cgroup: retry file writes on EINTR errors
After deploying a version of gvisor built with Go 1.14, we're seeing errors setting up cgroups (we manually run
runsc
viarunsc 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, we should retry writes that may fail with EINTR.This is also what runc does: opencontainers/runc#2258
