+Notes from python-dev
+=====================
+
+The python-dev discussion has been very fruitful.  Here are some
+in-progress notes from that thread which still needs to be reconciled
+into the body of the PEP.
+
+* Rarity of the use of this feature.  Important for distros but
+  probably much less so for individual users (who may never even see
+  these things).
+* Sibling vs folder-per-folder.  Do performance measurements.  Do stat
+  calls outweigh everything else?  We need to do an analysis of the
+  current implementation as a baseline.
+* Magic numbers in file names are magical; no one really knows the
+  mappings.  Maybe we should use magic strings (with a lookup table?),
+  e.g. 'foo.cython-27.py'
+* Modules should unambiguously name their __source__ and __cache__
+  file names.  __file__ is ambiguous.
