Might have found a sligh flaw with the "-O" option idea. The flaw is that it does not take an actual error (at least not one that ddrescue sees) to cause the slowdown. If there are difficult spots on the disk but no reported errors, it can still cause the reads afterwards to reduce speed.
If it helps, it is certainly possible to make ddrescue reopen the file after one or more slow reads.
Of course I would prefer to see the kernel fixed, or at least a explanation of why it slows down after an error.
