Not at all, in a renderer the Node and Chromium event loops are bound together, they’re part of the same v8 isolate, no IPC shenanigans.

The main process really shouldn’t be used for anything except setup. Since it controls gpu paints amongst other things, blocking on it will cause visible stuttering and a bad user experience.
