The --nowrite option will disable writing.  (It's not possible to
enable writing and disable reading, so that's the only option.)

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.
