#487 closed defect (fixed)

ipc_cleanup() may get new slammed phones that will prevent its completion

ipc_cleanup() first hangs up all slammed or connected phones, but lets connecting phones to finish the connect transaction, i.e. IPC_M_CONNECT_ME_TO. The idea is that it will hangup these connecting phones later, as soon as they get connected or freed. Now, in theory, the problem is that they can also get slammed by the other side just after the connection is established. In this case, ipc_cleanup() will be still waiting for those to become free or connected, but that will never happen, thus preventing ipc_cleanup() from ever finishing.
