Buffering in development suppresses output

Created by: chrismwendt

In local development, something is buffering stdout waiting for a newline, which makes it look like nothing is happening. That means if you write:

for {
  // tight loop
  fmt.Printf("%v", foo)
}

and you forgot the \n, then you might waste time tracking down why that line isn't getting executed.

cc @mrnugget in case this is under the purview of sg.
