+ * temporary asynchronously.
+ * So, if we're going to read from the span temporary, we need to idle before
+ * doing so.  But we don't need to idle after write, because the CPU won't
+ * be accessing the destination, only the accelerator (through 3d rendering or
+ * depth span reads)
+ * However, due to interactions from pixel cache between 2d (what we do with
+ * depth) and 3d (all other parts of the system), we idle at the begin and end
+ * of a set of span operations, which should cover the pix cache issue.
+ * Except, we still have major issues, as shown by no_rast=true glxgears, or
