Adeos doesn't implement OS scheduling, though other nanokernels do (see
exokernel paper for example.) One thing you can do with Adeos is build
the entire systems so that each OS only takes a certain portion of the
CPU. For example, you can modify the OS scheduler so that all active
tasks cannot take more that x% of the CPU time. You could also extend
Adeos to implement an OS scheduler a-la exokernel.
