On Linux, GOPROC_WORKLOAD_CGROUP places exec children in that cgroup before they run. The manager's environment owns this policy; per-exec environments cannot override it. The runtime must configure the cgroup and its memory limit.

Wait and Status report signal exits as 128 + signal (SIGKILL is 137), with stdout/stderr retained. A nonzero exit is process completion, not an RPC error.

to exec a process:

grpcurl -plaintext
-import-path ./proto
-proto goproc.proto
-d '{"args": ["ls", "-l"], "cwd": "/tmp", "env": ["FOO=bar"]}'
