Can you expand on what you're trying to do?

We have a 32 bit application that needs to create a 64 bit process to do processor intensive tasks and communicate with the main application typically hundreds of times per second, depending on the number of tasks. Passing shared memory objects and rights is also involved. Performance is critical, AppleEvents, distributed objects etc. seem too slow.

The recommended replacement is to have two launchd jobs, one which advertises a service with a well-known name in the bootstrap namespace.

We don't have a well-known name, that would have been the case for suggestion #2 in bootstrap.h, however this is not the case. In this case the name is dynamic and has no general purpose use for the system, in other words scenario #3 applies. To rephrase the original question for clarification: Is recommendation #3 in bootstrap.h regarding "sending a Mach send-right directly" technically accurate and valid? If yes, how does it envision sending a Mach send-right directly given the very fundamental principles and security constraints of Mach IPC?
