Notes
dyld maintains a list of Mach send rights to subscriber ports interested in image notifications (debuggers, sanitizers, code-signing daemons). This trap lets a caller atomically copy out the current set so it can iterate or replace it. It backs the task_dyld_process_info_notify_register interface used by lldb and by the kernel's userspace image change tracking.
