RFR 8028581: [TESTBUG] java/net/Socket/LingerTest.java failing

[Michael McMahon]

This is a test that just failed recently on Windows, probably due to a 
timing issue.
The critical time delay in the test is increased from 5 seconds to 10 
seconds
and some extra printlns are added to show the exact sequence in case it 
fails again.
