Sounds fine to me. Feel free to open a PR. Can you give an example of an expression that demonstrates this? |

As far as I know preview usually works on Windows. It's a bit difficult for someone else to write and test a PR if there is no way to reproduce the problem. You can use the |

That code runs fine here on OSX: In [10]: from io import BytesIO
...: obj = BytesIO()

In [11]: obj.seek(0)
Out[11]: 0
In [12]: obj.read()

Add "-nogs" option for dvipng call Add 10s timeout for subprocess calls

Add "-nogs" option for dvipng call
Hello,
recently I have discovered issue with printing/preview.py on Windows machine, that dvipng subprocess call is just infinite stuck (no time-out, when it is called). I was able to workaround it by adding "--nogs" option.
Could you, please, consider to add the same and also bound subprocess calls within some time-out.
