Hi,

I have update my Node-RED from v0.18.7 to v.0.19.4.  
Since this update, the file node sometimes signal an error when I would like to write data to a file (overwrite).

> failed to write to file: Error: write after end

```

Is this an Error in the file node, or is my flow incorrect?

add a delay node in before the File node and change it to 'Rate limit' and give it a 3 second delay.

I think the node is attempting to write to the file a second time before the system has had time to close the file.

As an interim solution that sounds like a pretty good idea. But if the node internally continues to work faster than it has finished the previous process, that sounds like a software bug in the node.

Hopefully that is the same bug as that addressed by this PR ?

Has this been fixed in latest version?

I noticed this problem in ver 0.19.4
