Code review comment for lp://qastaging/~cmiller/desktopcouch/default-context-gets-keyringclass-instance

I doubt it's due to this change, but I get this test-failure:

===============================================================================
[FAIL]: desktopcouch.pair.tests.test_couchdb_io.TestCouchdbIo.test_get_my_host_unique_id

Traceback (most recent call last):
