Meeting the application in user space

In modern programming environments, the increasing variety of programming models cannot be satisfactorily matched by a single operating system interface. An interface adaptable to specific application needs requires a user-level realization of system services. The operating system kernel should be reduced to minimal functionality, not biased towards a particular programming paradigm. To provide flexibility in the construction of interface families, we propose a system architecture based on a small set of orthogonal abstractions.
