Mmmmhh, it this is true then it would affect the order of how the "writeback buffers" are written to disk? If yes then I guess that this can potentially be dangerous (no assumption anymore of "1st come 1st served?")?

From the description it looks like it only throttles the new submissions while the writeback catches up.
