gmain: use atomic operation instead of GMutex to access g_main_context_default() (!1135) · Merge requests · GNOME / GLib

I think it is wasteful to use a mutex every time the default main context is accessed. Especially, as the default main context is used all the time.

I got triggered by the /* Slow, but safe */ comment.

Is this considered unsafe?
