a81020d505bf Add gethostname() and s.avail(). Guido van Rossum <guido@python.org> parents: 309 diff changeset	34 - no read/write operations (use send/recv or makefile instead)
896 6459e2f21bf6 Added {get,set}sockopt(). allowbroadcast is now obsolete. Guido van Rossum <guido@python.org> parents: 795 diff changeset	35 - setsockopt() and getsockopt() only support integer options
