Snapshot retaken with a native binary that counts the same monotonic clock the WebAssembly build counts (patches/0003). The guest was calibrating its TSC against a real rdtsc while it booted natively and then running on a nanosecond clock, so every sleep and timeout in the guest ran 3.3x long: 'sleep 10' took 33 s. It now takes 10.1 s, and the guest reports 1000 MHz, which is what it actually gets. Engine files unchanged.
