Well, clearly it doesn't work :). Please feel free to open another ticket. You are correct in saying that this is related to <http://tm.tl/4644>, but that ticket is specifically about a test, and the proposed solution there is to make the test sensitive. <http://bugs.python.org/issue7895> was the bug in Python that causes this, which has since been fixed. Although apparently the fix was not quite in time for 2.7, it looks to me like it has been committed to the 2.7 (and 2.6) branches, so perhaps we will see some point-releases which fix it. So in future versions of Python, Twisted will not be affected by this issue. However, it may be good to get a workaround in Twisted anyway, for those who have to deal with the combination of older Python / newer Setuptools, or a better fix, like changing the order of daemonization. So a ticket is definitely worthwhile. _______________________________________________ Twisted-Python mailing list Twisted-Python@twistedmatrix.com http://twistedmatrix.com/cgi-bin/mailman/listinfo/twisted-python
