A previous patch increased allocations by 15 bytes in order to ensure 16 byte alignment for g_malloc blocks. However, shared memory is already block aligned, and this extra 15 bytes caused allocation to fail when we were already allocating to the shared memory limit, which is a lot smaller than typical available RAM. Fix this by removing the alignment slack when allocating shared memory. https://bugzilla.gnome.org/show_bug.cgi?id=706066
