Issue #8567 : Fix incorrect precedence of signals in Decimal module.
...
When a Decimal operation raises multiple signals and more than one of
those signals is trapped, the specification determines the order in
which the signals should be handled. In many cases this order wasn't
being followed, leading to the wrong Python exception being raised.
This commit fixes those cases, and adds extra tests. The tests are
only enabled when EXTENDEDERRORTESTS is True, since they involve
rerunning each Decimal testcase several times.

fixed so that Decimal and float values that compare equal have equal
hash value.

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

valgrind -q --leak-check=yes --suppressions=Misc/valgrind-python.supp \

for i in `seq 1 4000` ; do
LD_PRELOAD=~/local/lib/libfailmalloc.so FAILMALLOC_INTERVAL=$i \

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

at reducing the size of the diff between the 2.x decimal.py

other way around
- make wording match on an exception message
