The Mad Science of Node
summary
Examples include a shared ArrayBuffer pointer that bypasses C↔JS overhead and saves about 30,000 extra JS calls per second for heavy crypto loads and lands in core, a live module reload system that works via global indirection but leaks old constructors and memory, and experiments with mutable native strings and pointer-swapping that yield small speedups but produce unpredictable corruption. Some hacks make it into Node core; others reliably explode.
