What really bugs me about Musl's refusal to support dclose is that the rationale is that _other_ libraries don't suppose safe unloading, so Musl shouldn't let you try. I don't like my libc to be paternalistic.

If Windows can do leak-free TLS with FreeLibrary, Musl can too. I'm sick of hearing "X is impossible" when some other system has been doing X for decades.
