            <em class="parameter"><code>share_context</code></em> already shares with,
            and the newly created context. An arbitrary number of
            rendering contexts can share data. However, all rendering
            contexts that share data must themselves exist in the same
            address space. Two rendering contexts share an address space
            if both are owned by a single process.
