The current limit is 512mb of cache for a certain SCSI cache controller
which was about to ship or maybe is already shipping. That's going
to be a large ``hole'' in a fs ... At least it will write data back
without OS intervention, so really only powerfails but not a freeze of
the machine will cause the worst case to happen.
