Errors in test suite Windows 2003 SP2

I'm getting some inconsistent errors in the test suite, mostly seems like
issues relating to wmi.py usage. I've tried upgrading the wmi.py and
pywin32 installations to the latest but that doesn't seem to help. Here's
two of the more consistent errors I've been getting: 

======================================================================

Number of CPUs test is going to fail on most platforms. From MSDN: 

NumberOfLogicalProcessors

    Data type: uint32
    Access type: Read-only

    Number of logical processors for the current instance of the processor. For
processors capable of hyperthreading, this value includes only the processors which
have hyperthreading enabled. For more information, see Remarks.

        Windows Server 2003, Windows XP, and Windows 2000:  This property is not
available.

Ok, I submitted changes to the test suite in r528 to fix the number of CPUs test. The
other test failures I'm seeing look like race condition issues, since they come and
go and different tests are failing each time. Based on the type of errors I'm seeing
it looks like WMI is unreliable for our purposes. Example error: 

======================================================================
ERROR: test_zombie_process (__main__.TestCase)

What's the current status on this?
If we can't rely on Windows specific tests based on wmi.py I suggest to 
determine the Windows version at runtime and skip those tests if it's == Windows 2003.

Username error was fixed in issue 114 (get_username() rewritten in C).
Other errors were fixed in r788 , r789 .

Status: Fixed
