No. Unix sockets cannot be reused. If the application that created the
socket via calling bind() for the path closed the socket, the socket
node is useless in the file system. Another bind() on it will return
ADDRINUSE and a connect() on it will return ECONNREFUSED. Only after it
was deleted it may be created anew with bind() and then be used again.
