All the new entries have (test_key_sock_t) ??
Anyway if you run the tests in the order they appear in 'test' script,
then it just so happens that the module will be loaded for
test_key_sock_t as it's first. I added the others just to cover the
cases where I sometimes run out of sequence, so you could remove these
if required.
