this seems to have broken builds without threads. After this commit I get a compile error: $ ./configure --without-threads --with-pydebug && make -j2 [...] ./python -E -S -m sysconfig --generate-posix-vars Could not find platform dependent libraries Consider setting $PYTHONHOME to [:] Could not import runpy module Exception ignored in: 'garbage collection' Traceback (most recent call last): File "/home/wolf/dev/py/py3k/Lib/runpy.py", line 16, in import imp File "/home/wolf/dev/py/py3k/Lib/imp.py", line 23, in import tokenize File "/home/wolf/dev/py/py3k/Lib/tokenize.py", line 28, in import re File "/home/wolf/dev/py/py3k/Lib/re.py", line 124, in import functools File "/home/wolf/dev/py/py3k/Lib/functools.py", line 22, in from dummy_threading import RLock File "/home/wolf/dev/py/py3k/Lib/dummy_threading.py", line 45, in import threading File "/home/wolf/dev/py/py3k/Lib/threading.py", line 6, in from time import sleep as _sleep ImportError: No module named 'time' Fatal Python error: unexpected exception during garbage collection

(Also having tests for this change would be nice.)
