[classlib][luni] Socket implementation is too slow
--------------------------------------------------

                 Key: HARMONY-4039
                 URL: https://issues.apache.org/jira/browse/HARMONY-4039
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Boris Kuznetsov


I noticed that Harmony classlib works too slowly with MySQL (both on DRLVM and Jrockit).
The reason is the socket implementation: availableStreamImpl uses 1 ms timeout for hysock_select_read().
It leads to 0.015 sec wait on select call for every available().

Here are the test which demonstrate the problem and proposed patch.

harmony-jre-r533500\bin\java test
estimatedTime 15625

After patch applying:
java test
estimatedTime 10
