The second release update to Node.js is out today.
“If someone new connects, then it executes the callback.” According the Node Web site, “Each connection is only a small heap allocation.”
Version 0.2.0 fixes several critical bugs including an OpenSLL 100 percent CPU usage on error bug. Node is now built with V8 2.3.8.
