Microkernels Should Support Passive Objects

We believe that a passive object model, in which the active entities
or threads migrate between passive objects, is more appropriate
than an active object model, as the basic structure of a
microkernel-based operating system. A passive object model provides
enhanced performance and simplicity because it is more
closely matched to the basic nature of microprocessors and the
requirements of applications. It also provides more functionality
by making the flow of control between objects a
first-class abstraction which can be examined, manipulated, and used
to carry information about the operation in progress.
