Yuck.
Do we have any idea how many kernels are out there that implement
fsync() as poorly as HPUX apparently does? I'm just wondering if we're
contemplating spending a whole lot of effort to work around a bug that
is only present on an (old?) version of HPUX. Do typical BSD derived
kernels exhibit this behavior? What about Linux? Solaris?
