This usually means that the system has run out of ephemeral ports or file descriptors. The proposed fix will catch the BindException, run the gc, wait a bit, and retry once. No guarantee that this will actually work - but maybe worth a try, though I worry a bit the authentication count might get wrong if the request that gets the BindException is the first one that follows the 401/407 response - in case the connection was closed after receiving 401/407. Since we have no visibility of which call to connect() fails, it is hard to cater for this possibility without making the test too permissive.
