Detect and delete locked file in python
<p>I want to detect whether a file is locked, using python on Unix. It's OK to delete the file, assuming that it helps detects whether the file was locked.</p>

<p>The file could have been originally opened exclusively by another process. Documentation seems to suggest that os.unlink won't necessarily return an error if the file is locked. </p>

<p>Ideas?  </p>
