// This is the multi core no atomics implementation. // This is the multi core no atomics implementation.

// The implementation handles the 32-bit rollover (every 49.7 days) by: // Without atomics, this implementation uses locks more aggressively:
// 1. Using a lock when detecting rollover to ensure atomic update // 1. Always locks when near the rollover boundary (within 10 seconds)
// 2. Restricting normal updates to forward movement within the same epoch // 2. Always locks when detecting a large backwards jump
// This prevents race conditions at the rollover boundary without requiring // 3. Updates without lock in normal forward progression (accepting minor races)
// 64-bit atomics or locking on every call. // This is less efficient but necessary without atomic operations.
