So taking out the extra release call doesn't help at all, that was a
shot in the dark. I checked and isReleasedWhenClosed is enabled, so
after I call [win close], I expect it to be released. Yet, I'm still
getting crashes in

I'm wondering if despite the release, the autoreleasepools still
retain the memory somewhere and expect it at this point (which is
after the dynamic binary has been unlinked. Is there a way to flush
the autorelease pools to test this theory out?
thanks,
