Hello,

I also second this ("thirded"? :-) ).

Setting $TMPDIR leads to strange effects like this:

  File "/usr/lib/python3.2/tempfile.py", line 216, in _mkstemp_inner
    fd = _os.open(file, flags, 0o600)
OSError: [Errno 13] Permission denied: '/tmp/tmp.daOkZV19Dm/ubtree0-build/tmpdir/tmp231sct'

This is a package build which runs tests during build, with $TMPDIR
set. As this initially gets created as root, the test suite is
apparently not able to access it.

Thanks,

Martin
