2.6.0: Oops in prune_dcache

[Dr. David Alan Gilbert]

The machine had been running 2.6.0 fine for a couple of days, and it
did this overnight - I think a few seconds after cron.daily started.
The machine is a Dual Athlon/MP on a Tyan S2460 motherboard; running
with IDE discs. Details and configs to anyone interested.
The machine still ping'd, but I couldn't ssh in, and the screensaver had
hung.
