Overview

Tracks whether a PROJ context is still alive. Shared between a Context and the finalizers of objects that depend on it (PjObject, Session). Because Ruby’s GC finalizer ordering is non-deterministic during shutdown, a dependent’s finalizer may run after its context has already been destroyed. Calling proj_destroy() in that situation segfaults (PROJ 9.8+). This object lets dependents check before calling into PROJ.
