Thank you for the clarification. In my system the user limit is 1024.

I can confirm that raise the current limit with:

```bash
$ ulimit -n 4096
```

fixed the problem.

I was trying to understand where these file are opened, and it seems
to me that the python code is always opening and closing all the
files, It is not clear to me which ctypes function is just opening the
files without closing them.
