The problem was that the randomly generated test data was occasionally
invalid.  Fix is to hardcode a specific set of test data instead of
using random.

weightedIntersection|Union(). That's a contradiction to the
documentation and the implementation.

Also change to use time.localtime() instead of calling time.time()
first.  This is a Python 2.1-ism.

Fix SF bug #516768 reported by Dave Wallace.

Replace use of PyMem_DEL() with PyObject_Del() on object dealloc
functions.  The use of PyMem_DEL() is incorrect for object
deallocation, because it only ever calls the low-level free().  If a
custom allocator like pymalloc is used, it needs to be called to free
the memory.

Also replace bare malloc() and realloc() with PyMem_Malloc() and
PyMem_Realloc().  I think this isn't a strict bug fix, but a would be
nice.  It guarantees that BTrees objects get their memory from the
same allocator as the Python core.

   The previous, insane version was passing None or a thread id to "%.03f".

Add some whitespace around get_transaction() implementations.

The code was intended to be added to the Zope3 branch, not modified on
the trunk.

code that is needed for it yet.

Summary of changes:

- Add function gc_all_items() to call gc_item() on everything in
  dict.  This factors out common code in all the gc methods.

- Add check_size() function that factors out code to check cache size
  before starting a gc.

- Simplify argument processing in cc_invalidate(), avoiding a second
  call to PyArg_ParseTuple() when argument is a sequence instead of a
  dictionary.

- Chance code to reflect belief that NULL return from PyDict_GetItem()
  does not set exception, except in cases that don't apply for the
  pickle cache like comparing a string with high-order bit set to a
  Unicode object.

- Use if (!expr) instead of UNLESS().

- Remove all statements from conditionals.

- Reformat to 4 spaces and Python-style brace placement.

- Put whitespace around operators and after commas.

Refactor main() to report all errors and exit with non-zero status.

Remove useless -d option.
