-The Collaborative International Dictionary of English v.0.48
-defines a mechanism as:
-
-> The series of causal relations that operate to produce an
-> effect in any system; as, the mechanism of a chemical
-> reaction.
-
-This is, a mechanism is a function that produces some result.
-As mechanisms determine the type of result, they necessarily
-impose some [[policy]] (rules). Mechanisms that are referred
-to as policy-free are those that minimally impose policy.
-
-A process can be used to encapsulate a program instance. On Unix,
-a process is associated with a UID. This UID, in part, determines
-what the process is authorized to do. On a [[microkernel]],
-the policy that controls what resources a process may access
-are realized separately. This may achieved through the use of
-UIDs, however need not. Thus, the processes mechanism on such
-microkernels impose less policy than on Unix. A process is not
-policy free as it is possible to use other mechanisms to
-encapsulate a program instance, e.g., [[SFI]] and tainting
-ala [[Asbestos]]. \ No newline at end of file
