Tests is frozen on ABCL and CCL on macOS

Start by reproducing the test suite on macOS with ABCL and CCL, focusing on the listed USOCKET-TEST cases where execution freezes or reports incorrect conditions. Compare the failures in SOCKET-FAILURE, SOCKET-LISTEN, NS-HOST-NOT-FOUND-ERROR, TIMEOUT-ERROR, and the UDP test; done means the suite completes without freezing and these expected conditions pass.

An attempt to run test on ABCL on macOS leads to inifity freez. Console output:
