Reminds of the issues we had with Ruby on Rails and it's (at the time)
very mysql-centric tools that made us take a fork to large portions of
its brain to get things like this working. Worked with a developer
for a day or two fixing most of the worst mysqlisms in RoR at the time
to just get this kind of stuff working.

Yeah, I'd probably resort to fsync off in that circumstance too
especially if syn commit off didn't help that much.
