Moreover, Nemesis has been designed such that these Quality of Service guarantees are meaningful: In a microkernel environment, an application is typically implemented by a number of processes, most of which are servers performing work on behalf of more than one client. This leads to enormous difficulty in accounting for resource usage. In a kernel-based system, multimedia applications spend most of their time in the kernel, leading to similar problems.
