That's not what I've said. There is no applications not working due to this
bug.
There is a win9x DLL. That effectively makes this bug invalid, since we can't
fix the bugs in Windows DLLs, or add win9x specific behaviour to make one
broken
win9x DLL work although built-in DLL which works just fine.

Your test case shows that.

There could be a lot of reasons leading to 100% cpu usage, there is no need
to speculate about that.
