Fsync patches could possibly be improved more by those that know wine code the
best - WineHQ devs :)

But yes, it is not without flaws, and it is hard to quantify real performance
benefits. When using Wine for games - every FPS counts, and every uS less
latency counts, but the cost probably being as you say a maintenance burden.

If native Linux games starts using this call and can show improvements by doing
so, maybe the argument can be had again in the future :)
