TESTED=./python -E -tt ./Lib/test/regrtest.py -uall (both debug and opt modes)

  Fix:
   * crashes on memory allocation failure found with failmalloc
   * memory leaks found with valgrind
   * compiler warnings in opt mode which would lead to invalid memory reads
   * problem using wrong name in decimal module reported by pychecker

  Update the valgrind suppressions file with new leaks that are small/one-time
  leaks we don't care about (ie, they are too hard to fix).

  TESTED=./python -E -tt ./Lib/test/regrtest.py -uall (both debug and opt modes)
    in opt mode:
    valgrind -q --leak-check=yes --suppressions=Misc/valgrind-python.supp \
      ./python -E -tt ./Lib/test/regrtest.py -uall,-bsddb,-compiler \
                          -x test_logging test_ssl test_multiprocessing
    valgrind -q --leak-check=yes --suppressions=Misc/valgrind-python.supp \
      ./python -E -tt ./Lib/test/regrtest.py test_multiprocessing
    for i in `seq 1 4000` ; do
      LD_PRELOAD=~/local/lib/libfailmalloc.so FAILMALLOC_INTERVAL=$i \
          ./python -c pass
    done

  At least some of these fixes should probably be backported to 2.5.
