GTK calls must be done on the context of the same task/thread running the
messages loop.

Special is GTK, GDK, Gobject, GIO and the rest, which are not
multi-threaded.
I don't think it must be the main task of the process, it could be any
task, but just one task.
I didn't try GTK running on a non-main task, because it would not make much
sense anyway. It is possible that Mac OS could have some limitations on
this, that depends on the Mac OS GDK backend. I doubt it is the case,
though.
