Subject: Use the dummy_thread module in Queue.py and tempfile.py.
X-Git-Tag: v2.3c1~2783
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a0934246d3ee4061e93805d056759f3f40ec45de;p=thirdparty%2FPython%2Fcpython.git

Use the dummy_thread module in Queue.py and tempfile.py.
tempfile.py already contained code to let it run without threads present;
for Queue.py this is considered a useful feature too.
