- PC/VC6/_bsddb.dsp:
    removed '/nodefaultlib:"msvcrt"' to fix linker error.

- PC/VC6/_msi.dsp:
    added new module support.

- PC/VC6/_sqlite3.dsp:
    /D "MODULE_NAME=\"sqlite3\""
    caused extra leading space like
    #define MODULE_NAME " sqlite3"
    so uses
    /D MODULE_NAME=\"sqlite3\"
    instead.

- PC/VC6/python.dsp:
    changed stack size to 2MB to avoid stack overflow on
    some tests.

Issue #2113: Fix error in subprocess.Popen if the select system call is
interrupted by a signal.

Issue #1471: Arguments to fcntl.ioctl are no longer broken on 64-bit OpenBSD
and similar platforms due to sign extension.

Issue #3120: On 64-bit Windows the subprocess module was truncating handles.

- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword
  argument in python 2.5, this broke code that subclassed Popen to include its
  own poll method.  Fixed my moving _deadstate to an _internal_poll method.

Issue #2620: Overflow checking when allocating or reallocating memory
was not always being done properly in some python types and extension
modules.  PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
all been updated to perform better checks and places in the code that
would previously leak memory on the error path when such an allocation
failed have been fixed.

This is a backport of r65005.

- Issue #2632: Prevent socket.read(bignumber) from over allocating memory
  in the common case when the data is returned from the underlying socket
  in increments much smaller than bignumber.

When a thread touches such an object for the first time, a new thread-local __dict__ is created,
and the __init__ method is run.
But a thread switch can occur here; if the other thread touches the same object, it installs another
__dict__; when the first thread resumes, it updates the dictionary of the second...

This is the deep cause of the failures in test_multiprocessing involving "managers" objects.

An instance of a weakref subclass can have attributes.
If such a weakref holds the only strong reference to the object,
deleting the weakref will delete the object. In this case,
the callback must not be called, because the ref object is being deleted!
