Dynamic program monitoring and transformation using the OMOS object server

By implementing an executable image loader as a persistent user-space program, system program loading capabilities can be extended. The authors present OMOS (Object/Meta-Object Server), which provides program loading facilities as a special case of generic object instantiation. They discuss the architecture of OMOS, the extensible nature of that architecture, and its application to the problem of dynamic program monitoring and optimization. Several optimization strategies and the results of applying these strategies are outlined.
