Code review request 8037346, Need to terminate server process if client runs into problems

[Xuelei Fan]

Hi,

Please review this test fix:

webrev: http://cr.openjdk.java.net/~xuelei/8037346/webrev.00/

Tests fix. If client runs into problems, the server side may be blocked
on socket.accept().  This fix set SO_TIMEOUT to 5 seconds for each
server socket, so that if client runs into problems, the server will
terminate itself within 5 seconds.

Thanks,
Xuelei
