I can't wait! I will promptly get the centerfold (a gorgeous front view of a
Zilog Z80) and hang it right next to my Manischewitz chicken soup poster! <g>
Let me think about this. This goes to xxx as well. I think some kind of
"mirror" could help. A mirror copy of the system tables could be kept
some place else. In case the master table gets screwed, just replace with the
copy (though you would loose anything created after the last copy was done).
This could be done in such a way that every write operation would check the
consistency of the table and update the mirror. This would add some processing
time but for writing only (which isn't really that bad). Reads wouldn't
change.
