Resolve issue #939
This bug is caused by fq which can terminate pipe before sending all frames of a message first. So sometimes two messages were mixed and this confused ZAP handler. This patch just modifies one pipe parameter so that socket consumes all messages before dropping the pipe.
sockets created by accept are leaked to child processes (ticket #956)
