Concerning the C&C (copy and compare(?)):
The DB is not comparing the object on an element by element basis, is it?
Is it doing a memory contents comparison?
Does the object contain a "magic number"?
Does this copy and compare include object method code?
I'm thinking of using a "magic-number" marking to determine whether my objects
are dirty in cache. Can you point me to any quick and dirty guaranteed algorithms
for this? Quite possibly they may be exist somewhere in my Linux kernel source?
And just for giggles. Suppose I return to discussing the server model that runs
a full language implementation ala Cold/LPC and possibly yours and Nathan's.
Any thoughts on multi-threading the language implementation?
What happens when the same objects method is called by a second thread?
Does this entail writing fully renterant and reusable code in the server
language implementation?
