Libuv loaded and unloaded the Core Services and Application Services for every call to uv_set_process_title(). Change that to load them on the first call to uv_set_process_title() and delay unloading until libuv is unloaded. Speeds up process_title_threadsafe by about 10x on my system. It should fail less often (hopefully not at all) on the CI now. PR-URL: https://github.com/libuv/libuv/pull/2480 Reviewed-By: Saúl Ibarra Corretgé <s@saghul.net>
