Function die_with_parent

crates/openshell-driver-vm/src/procguard.rs:42–44

Cross-platform "die when my parent dies" primitive. The VM driver spawns a chain of subprocesses (compute driver → `--internal-run-vm` launcher → gvproxy + libkrun fork). If any link in that chain is killed with SIGKILL — or simply crashes — the children are reparented to init and survive indefinitely, leaking libkrun workers and gvproxy instances. This module exposes two functions: [`die_with_p

/// that needs to drain state; we are a VM launcher / gRPC driver whose
/// entire job is tied to the parent's lifetime.
pub fn die_with_parent() -> Result<(), String> {
    die_with_parent_cleanup(|| ())
}

/// Like [`die_with_parent`], but run `cleanup` before terminating.
