stream: writes may return false but forget to emit drain

If a write is above the highWaterMark, _write still manages to
fully send it synchronously, _writableState.length will be adjusted down
to 0 synchronously with the write returning false, but 'drain' will
not be emitted until process.nextTick.

If another small write which is below highWaterMark is issued before
process.nextTick happens, _writableState.needDrain will be reset to false,
and the drain event will never be fired.

So we should check needDrain before setting it up, which prevents it
from inproperly resetting to false.

We are in an unrecoverable state if v8 throws a FatalError, actually
ask the operating system to dump core in this case.

doc: streams must be open to be passed to child

spawn stdio options can be a 'stream', but the following code
fails with "Incorrect value for stdio stream: [object Object]",
despite being a stream. The problem is the test isn't really
for a stream, its for an object with a numeric `.fd` property,
and streams do not have an fd until their async 'open' event
has occurred. This is reasonable, but was not documented.

      'ignore',
      fs.createWriteStream('out.txt',{flags:'a'}),
      'ignore']})
