I have process A, which is doing a lot of `console.log`. Process B `process.spawn`s A, does `a.stdout.on('data', ...)`, but not all of A's output is actually making it to that callback. I think Node is exiting before its own buffers are flushed? Why and how do I make it stop?

The context here is: I have a test runner. When a test fails, it does `process.exit(1)`. But that means that any failing test that prints a lot of data to stdout or stderr will have some of it silently truncated. And it only happens sometimes.

This is really blowing my mind. "Send things across a pipe when they're written to stdout" is one of the most fundamental Unix things, but Node can't do it. Yet it was marketed as being Unixy from the very beginning.
