Manual profiling with cleanup
This demonstrates manual profiling with cleanup: 1) Ensures profiling always stops properly, 2) Uses try-finally for guaranteed cleanup, 3) Prevents profiling leaks, 4) Provides accurate timing measurements, 5) Robust error handling, 6) Suitable for production code, 7) Maintains profiling integrity, 8) Common pattern in performance monitoring systems.
