8666,boost::lockfree::spsc_queue::emplace_push,aubrey@…,timblechmann,"It would be nice to be able to write the following function:
{{{
void producer_thread()
{
    while(isRunning)
    {
        T& item = q.emplace_write(); // This feature avoids the need to create the item
        write(item);
        q.emplace_push(); // This feature avoids the need to copy the item
    }
}
}}}

Implementing this:
A slow consumer may be reading the item after the write index so the change is not as easy as exposing the next item.  The change would require a gap of 1 item to always exist to avoid a read/write collision.
