stdout maxBuffer exceeded when using 4.0.0

[mdarveau]

I get the following after I upgraded to 4.0.0:

 "stream": "stdout",
  "name": "Error",
  "message": "stdout maxBuffer exceeded",
  "stack": "Error: stdout maxBuffer exceeded\n    at PassThrough.stream.on (/Users/mdarveau/perso/workspace/maligue/node_modules/gulp-mocha/node_modules/get-stream/index.js:30:12)\n    at emitOne (events.js:101:20)\n    at PassThrough.emit (events.js:191:7)\n    at readableAddChunk (_stream_readable.js:178:18)\n    at PassThrough.Readable.push (_stream_readable.js:136:10)\n    at PassThrough.Transform.push (_stream_transform.js:128:32)\n    at afterTransform (_stream_transform.js:77:12)\n    at TransformState.afterTransform (_stream_transform.js:54:12)\n    at PassThrough._transform (_stream_passthrough.js:21:3)\n    at PassThrough.Transform._read (_stream_transform.js:167:10)\n    at PassThrough.Transform._write (_stream_transform.js:155:12)\n    at doWrite (_stream_writable.js:329:12)\n    at writeOrBuffer (_stream_writable.js:315:5)\n    at PassThrough.Writable.write (_stream_writable.js:241:11)\n    at Socket.ondata (_stream_readable.js:557:20)\n    at emitOne (events.js:101:20)\n    at Socket.emit (events.js:191:7)\n    at readableAddChunk (_stream_readable.js:178:18)\n    at Socket.Readable.push (_stream_readable.js:136:10)\n    at Pipe.onread (net.js:559:20)\n",
  "showStack": false,
  "showProperties": true,
  "plugin": "gulp-mocha"

I do log a LOT of data and I get this error when the output reach ~10MB. The execa lib that is used claim to support sysout up to 10MB.

Thank you!
