Perhaps more to the point: all this is predicated on an assumption no
longer particularly valid, which is that the kernel's ideas about disk
write scheduling matter at all. A decent SCSI disk drive will pre-empt
the kernel's ideas anyway by absorbing as many pending writes as it can
and then doing its own write scheduling. fsync won't affect the drive's
choices in the least, only allow us to find out when the drive is done.

TIP 4: Don't 'kill -9' the postmaster
Perhaps totally unrelated, as i've only read the last couple of posts on this, but what does Postfix (the MTA) do? How does it handle this?
I trust Wietse implicitly to DTRT. If it were me I would ask him how he handles the writes or at least check the Postfix src. *shrug* Just an idea.
