Abstract
Methods, systems, apparatuses and program products for providing for communications within a computing environment that provides for execution isolation, especially a DXE (Driver Execution Environment) phase of a PC (personal computer) startup process. Provision is made for blocking of server threads awaiting service requests and blocking client thread awaiting server responses, together with marshalling formal parameter descriptions and service request/response arguments across disparate execution contexts that disallow simple data redirection between them.
