// Exit while Node has OpenSSL work in flight (node-island-exit.test.ts):
// Node must stop its threads before the process's exit handlers tear
// OpenSSL down. argv[2]: "early" (exit right after Node starts, while it
// loads the system root certificates on a thread of its own with
// NODE_USE_SYSTEM_CA=1), "load" (node:tls loaded, extra certificates
// loading off-thread), "exit" (process.exit with pool work in flight),
// "keys", or "return" (fall off the end). A "-return" suffix ends the
// program by returning instead of process.exit (C exit and its handlers).
