Struct SpawnClaim 

pub struct SpawnClaim { /* private fields */ }

The claim around one process spawn attempt, backed by an OS exclusive lock on spawn.claim. The lock lives as long as the open file: the kernel releases it when the owner dies (any signal), and there is no time-based eviction of a live owner. The file is never unlinked, so every contender always locks the same inode; Drop closes only this claim’s own handle.
