Memory Domain.
A memory domain is a collection of memory partitions, used to represent a user thread's access policy for the linear address space. A thread may be a member of only one memory domain, but any memory domain may have multiple threads that are members.
Supervisor threads may also be a member of a memory domain; this has no implications on their memory access but can be useful as any child threads inherit the memory domain membership of the parent.
A user thread belonging to a memory domain with no active partitions will have guaranteed access to its own stack buffer, program text, and read-only data.
