-# c.f. ticket #455, there is a problem in the intersection of setuptools,
-# twisted's setup.py, and nevow's setup.py . A Tahoe build, to satisfy its
-# dependencies, may try to build both Twisted and Nevow. If both of these
-# occur during the same invocation of 'setup.py develop', then the Nevow
-# build will fail with an "ImportError: No module named components". Running
-# the build a second time will succeed. Until there is a new version of
-# setuptools which properly sandboxes sys.modules (or a new version of nevow
-# which doesn't import twisted during its build, or a new version of twisted
-# which doesn't import itself during its build), we just build tahoe twice
-# and ignore the errors from the first pass. Updated 16-Sep-2008: now we need
-# three invocations.
