No other AFS port is known to have such dramatic or frequent lossage
when a machine experiences an unclean shutdown.  It's common practice
to use stop-A and "boot" to reboot cluster suns, for instance.

However, you're probably right that it's probably not AFS's problem.
I suspect that it's because ext2fs doesn't make even a vague attempt
at staged writes like FFS does.
