The active process is stopped in the snapshot primitive (a.k.a. "image saving") and resumes after it on startup. All other processes are waiting on some semaphore anyway.

Not the process itself. But you surely keep the process in a class somewhere, and the class can arrange to get notified on startup by adding itself to the startup list. See addToStartUpList:.

Delays get adjusted after resuming from snapshot. So it should just work.
