Summary: Memory leak on SWbemRefresher

Initial Comment:
Got a memory leak problem on getting performance data from wmi. For example, when running code below, it can be found in windows task manager that memory usage continue grows.

import win32com.client

com = win32com.client.Dispatch("WbemScripting.SWbemRefresher")
obj = win32com.client.GetObject("winmgmts:\\root\cimv2")

while True:
    com.AddEnum(obj, "Win32_Process")
    com.DeleteAll()

Message:
We have some leak detection code in the win32com test suite and as the loop
you show is so simple (just 2 method calls), I'm afraid I must conclude the
leak is in WMI itself.  Maybe you could see if a WScript script does the
same thing?
