Print statements are sometimes delayed until running the cell a second time

[markwatsonatx]

I created the following cell:

%%node
print(new Date());

Sometimes this works without issue. Sometimes the value is not printed. Running the cell a second time results in two printouts:

%%node
print(new Date());

"2017-08-29T21:09:40.994Z"
"2017-08-29T21:09:46.047Z"

Not just limited to using the print command in the cell. I reproduced with the help command as well:

Hi @markwatsonatx. I'm struggling to reproduce this on my notebook. What version of Node / pixiedust are you using?

[markwatsonatx]

PixieDust 1.0.10 Node 8.4.0

I wish I had good reproducible steps. It is very intermittent.
