+Restricted the ``isal`` test dependency to CPython, since

+build requires ``nasm``, which is not available on the CI

+changes -- by :user:`bdraco`.

+Fixed a flakey ``test_tcp_connector_fingerprint_ok`` by aborting
+the SSL shutdown on the test's TCP connector before returning.
+The graceful TLS close was occasionally outliving the test event
