File saved with different user on Linux
#### Code Sample, a copy-pastable example if possible

```python

import dataframe ... then ..
dataframe.to_excel('path_to_save.xlsx')

# Your code here

```
#### Problem description

I'm executing an easy **foo.py** script containing 1 simple function.
1) Read a xlsx file, via pd.read_excel
2) Save it again. 

While I'm running the foo.py file on linux machine by **root01** user, I see that the new saved .xlsx file **is not owned by me**, but by **root**. So in other scripts, following this foo.py, I got in troubles, due to this change of ownerships happened inside foo.py writing phase.]
