lat_connect is a client/server program that measures interprocess connection latencies. The benchmark
times the creation and connection of an AF_INET (aka TCP/IP) socket to a remote server. Care is take
that the connection time does not include any other overhead, such as the gethostbyname() or remote port
lookups since these add more overhead than the connection establishment itself.
lat_connect has three forms of usage: as a server (-s), as a client (lat_connect localhost), and as a
shutdown (lat_connect -S localhost).
