I suppose though that this is the best that can reasonably be done in
this situation however...
I spent a few days looking for alternatives, and indeed I found
nothing better...
Just an off the top of my head crazy idea...
Could you leave the error bit set on the page and treat it as a dirty
bit during a future msync, clearing the error bit at that point.
The general idea would be to leave the error set unless an explicit
write was requested.
