[IronPython] print is not thread safe ?

[Dino Viehland]

I think this really means that file is not thread safe.  I agree that it should be thread safe, I've opened CodePlex bug 16623 (http://www.codeplex.com/IronPython/WorkItem/View.aspx?WorkItemId=16623) to track the issue.  Thanks for the report!

FWIW we've sometimes seen this, although it is hard to reproduce
reliably. 'print' really ought to be thread safe...
