Change subject: subprocess: maintain a thread for fork/exec ...................................................................... subprocess: maintain a thread for fork/exec If SubprocessServer::Init() is called from a short-lived thread, because it does a fork/exec, the subprocess will silently be reaped when the thread exits. Specifically, we saw this happening upon initializing the CatalogManager, which happens in a short-lived thread, when starting up the Ranger client. This surfaced as us getting an EOF from the subprocess receiver thread.
