Standard out sometimes failing to output *before* error/exception for node-v0.10.3-x64

I've come across this issue in a few places while experimenting with nodejs the past few days. The issue is pretty simple and is documented here:

This sounds like a dup of #3584.

Looks likely. I am on windows.

Note that the following does not cause this problem:

Looks like someone submitted a fix. I'm working around it by using this function:

var fs = require('fs');
function log(m) {
  fs.writeSync(process.stdout.fd, m+"\n");
};

log("test");
log("test");
throw Error("test");

Perhaps the fix is simply to implement console.log and the like using this kind of file descriptor writing mechanism

Well, console.log and friends are already supposed to be blocking iff stdout/stderr is a tty or a file (but not a pipe to another process.) If you're seeing - or rather, not seeing - dropped messages, that means something is not working as expected.

Appears to have been fixed.
