staticDeinitialize not called in IE

[GoogleCodeExporter]

I can observe strange behavior when browser is shutdown: staticDeinitialize is 
not called, sometimes...
because of this FB::Log::stopLogging() not called.
STDAPI DllCanUnloadNow(void)
{
hr==S_FALSE==>HRESULT hr = _AtlModule.DllCanUnloadNow(); 
    if (hr == S_OK && isStaticInitialized()) {
        getFactoryInstance()->globalPluginDeinitialize();
            FB::Log::stopLogging();
            flagStaticInitialized(false);
    }
    return hr;
}

What is the expected output? What do you see instead?
expected call PluginCore::StaticDeinitialize

What version of FireBreath are you using? On what operating system and browsers?
git revision f8a15d23c062ae74e9b2b4e76e8e41375102736f
Windows 7-32bit, IE 8

What version of your compiler or IDE are you using?

Please provide any additional information below.
I have 2 pages with slightly different javascript code and the same plugin 
initialization routine. At one plugin shutdown is correct but at another as 
described above.

Is there any thought in what direction to investigate?

Hmm.  not at present; it shouldn't unload the module if that returns false, I'd 
imagine.  We need to figure out why it is returning false (thus preventing the 
deinitialization).  I can't reproduce this myself...

ie9-32bit win7-32bit  vs2008sp1
when use ie9-32bit open a new web page tab with plugin and then close it, the 
function DllCanUnloadNow is not called, so staticDeinitialize is not called. If 
you open the web page tab there are other web page tab, then close the page 
plugin, the function DllCanUnloadNow is called.
