I'm not sure how expensive this call is for the other platforms, but IPC/Mojo is
only used when we are in multi-process mode so we might want to scope it:
#if defined(REMOTING_MULTI_PROCESS)
    mojo::edk::Init();
#endif

+1
It's also likely to affect binary size, as we don't currently use mojo on other
platforms

Done.
