Reply To: Security of Self-Services & Inheritance

For most services I see work that can’t be done in the context of the requesting call being done in interrupt driven threads. One factor, a thread from process A may have access to perform the service for A, but not for process B when running service code.

Accounting time in a service to other than the nominal owner of a thread is hard if you don’t trust the service on the matter. In a general case one process (system scheduler in this case) knows little of how another works.
