- * clnt_tcp.c, Implements a TCP/IP based, client side RPC.
- *
- * Copyright (C) 1984, Sun Microsystems, Inc.
- *
- * TCP based RPC supports 'batched calls'.
- * A sequence of calls may be batched-up in a send buffer. The rpc call
- * return immediately to the client even though the call was not necessarily
- * sent. The batching occurs if the results' xdr routine is NULL (0) AND
- * the rpc timeout value is zero (see clnt.h, rpc).
- *
- * Clients should NOT casually batch calls that in fact return results; that is,
- * the server side should be aware that a call is batched and not produce any
- * return message. Batched calls that produce many result messages can
- * deadlock (netlock) the client and the server....
- *
- * Now go hang yourself.
