Gee. When you say ``Postfix,'' are you referring to the same MTA that
incorrectly skips some essential fsyncs, because the MTA author didn't
understand that write-fchmod-fsync often writes the inode first?

You know, I can save _tons_ of writes by storing mail on a RAM disk! Why
am I bothering to implement a fast journaling filesystem for qmail 2,
when I could simply pretend that the power never goes out?
