-- t'GI.Gio.Objects.MemoryOutputStream.MemoryOutputStream' is a class for using arbitrary
-- memory chunks as output for GIO streaming output operations.
-- 
-- As of GLib 2.34, t'GI.Gio.Objects.MemoryOutputStream.MemoryOutputStream' trivially implements
-- t'GI.Gio.Interfaces.PollableOutputStream.PollableOutputStream': it always polls as ready.
