It would be nice if this:

process.stdin.pipe(process.stdout);

were equivalent to cat. However, since stdin starts out in a paused state, this does nothing, and you have to do:

process.stdin.pipe(process.stdout);
process.stdin.resume();

which is 100% more lines of code. I find that rather objectionable.

Options:

1. Stream.prototype.pipe should call this.resume() after setting up the destination. This would be the fix for other streams exhibiting the same problem, but would have much further reaching side effects. I'm very wary about doing this for 0.8, but it could be explored for 0.9.
2. process.stdin.pipe should call this.resume() after applying Stream.prototype.pipe. This would be the surgical fix, but is perhaps still too hazardous to do now for 0.8 without exploring edge cases.
