Berrang=C3=A9 While code is supposed to call qio_channel_close() before releasing the last reference on an QIOChannel, this is not guaranteed. QIOChannelFile and QIOChannelSocket both cleanup resources in their finalizer if the close operation was missed. This ensures the TLS channel will do the same failsafe cleanup.
