-- On FreeBSD, the bundled glog Mutex destructor (via pthread_rwlock_destroy)
-- returns EBUSY when rwlocks are still held at process exit, causing abort(9).
-- This build-time code generator has fully completed when main() returns, so
-- it is safe to skip C++ static destructors by calling _exit() directly.
