Bug: PyFlake command writes files

[wolph]

Right now whenever I run PyFlake the file is immediately written to the filesystem, the result is that when I'm simply checking the file it automatically writes to the filesystem which (in the case of syntax errors) results in my development server crashing because it auto-reloads on file changes.

If the command has to write for it to work, can it write to a temporary file instead perhaps?
The better solution would be to pipe the data straight towards the flake8 stdin imho, but not sure if that's too easy to integrate into the current script.

The flake8 command at least supports this using the following syntax:

cat some_python_file.py | flake8 -
