+Subject: [PATCH] curl: Make socket callback during cleanup into no-op
+
+Because curl_multi_cleanup may invoke callbacks, we effectively have
+some circular references going on here. See discussion in
+
+https://github.com/curl/curl/issues/14860
+
+Basically what we do is the socket callback libcurl may invoke into a no-op when
+we detect we're finalizing. The data structures are owned by this object and
+not by the callbacks, and will be destroyed below. Note that
+e.g. g_hash_table_unref() may itself invoke callbacks, which is where
+some data is cleaned up.
