29  ### stolen from twisted.python.reflect and changed 
30  ### the version in Twisted 1.3.0 checks length of backtrace as metric for 
31  ### ImportError; for me this fails because two lines of ihooks.py are in 
32  ### between 
33  ### filed as http://www.twistedmatrix.com/users/roundup.twistd/twisted/issue698 
34  ### remove this when fixed and depending on new upstream twisted
