      Description

        In the test

        java/lang/Runtime/exec/StreamsSurviveDestroy.java

        Thread.sleep(100) is insufficient on slow sparc machines in -Xcomp mode. For instance, on vm-b1600s-1.sfbay the test fails like this (a couple of attempts might be needed to reproduce):

        /net/sqenfs-1.sfbay/export1/comp/vm/jdk/hsx/16/pit/b06/jdk7b65/product/solaris-sparcv9/bin/java -d64 -server -Xcomp -XX:-PrintVMOptions StreamsSurviveDestroy

        test
          EOF
          exit: 15
        Exception in thread "main" java.lang.Exception: out: Exception thrown

                at StreamsSurviveDestroy.main(StreamsSurviveDestroy.java:176)

        Increasing sleep time to 1000 helps.
