It would be more correct to say that V8 has a 1G memory limit. But node.js actually gives you these nice things called Buffers which, according to the node.js manual, are "similar to an array of integers but corresponds to a raw memory allocation outside the V8 heap" (see http://nodejs.org/api/buffers.html http://nodejs.org/api/buffers.html). Buffers are used all over the place in node, which should mitigate the degree to which this is actually a problem. Even if this bug report stays a wontfix, it won't affect my decision to use node because of Buffer support.
