Not sync metadata on O_SYNC writes.
That's also dangerous -- might cause data corruption after crash. It is mostly
a hack if you know your programs very well, but can't change them
to use O_DSYNC when they only need that.
Also his other options basically all just use more memory. If you
have a P90 you're likely low on memory for modern standards and
shouldn't use them.
