 I added fsync() on directories to exim-3.31, it took about 2hrs
coding and another hours testing it (with strace) to make sure it was
doing the right thing. That was from almost never seeing the source
before.
 The only reason it took that long was because that version of exim
altered the spool in a couple of different places. Forward porting to
3.951 took about 20minutes IIRC (that version only plays witht he
spool in one place).
