relax SVN archive

The command used was:
2to3 -w \
-x except \
-x import \
-x imports \
-x long \
-x numliterals \
-x xrange \
relax .

This is from the docs/2to3_checklist document. Two print statements changed in multi/processor.py
had to be manually fixed afterwards, as the end and file args to the print statement do not exist in
all python 2.x versions.
