Should Keykos have an operation on a domain that emasculates it to avoid the cost of creating a new domain?
Perhaps a factory could recycle a domain that it recognizes so as to avoid some of the creation cost.
There is a valid security principle of cleaning after use, at least before reallocating some limited resource to a new situation.
We clean page both disk page frames and core page frames before reallocation thru various kernel hacks.
The current system never reallocates domains; it merely tears them down only to reconstitute them from scratch (buying pages and nodes again).
There are these variations on the proposal:
- Strip down a domain to its three nodes; this is something a domain creator might do, preserving only the brand.
General keys, address-space, meter and register values are zapped.
- Preserve .program and initial PSW.
The factory might do this to reallocate a domain returned to the factory.
- An operation that the domain’s own program might perform to cleans itself between invocations of possibly diverse interests.
