Calling g_main_context_invoke() will ensure that the main context is
owned and acquired during the invocation. As I said, it will do the
right thing depending on the type of context you are using.

Correct, but remember that different libraries may have different
contexts in different threads already by the time you call your code.

It's also a good rule of thumb to start using this function, as it
will be more efficient once you start using API like GTask, with its
own main context.

Ciao,
