Always possible.  I didn't report this until I had replicated the crash 
and seen exactly the same thing twice.  I've seen it crash on this 
assertion 6 times now.  Bad hardware is not normally so consistent.

I do have another system that's almost identical to this one, except for 
the hard drives.  If progress on tracking down the problem stalls I can 
try to duplicate this on there.

I kicked off another test that includes the block number just before Tom 
suggested it, so I should have the block by tomorrow at the latest.  The 
range of runtime before crash is 3 to 14 hours so far.
