      Description

      Sometimes ( ~ 3% of runs) nsk/coverage/arguments/arguments008 hangs.
      It runs JVM with -Xprof flag.

         Steps to reproduce:

      1. Take Solaris (x86) box
      2. Prepare testlist with 100 items:
           for i in {1..100}; do echo "nsk/coverage/arguments/arguments008 execute_positive quick,jpda,hprof" >> testlist.run.100; done
      3. execute test:
           /net/vmsqe.ru.oracle.com/export/gtee/bin/ute -bits d64 -jdk $JAVA_HOME -vmopts '-server -Xmixed' -component vm -tlists empty -testlist testlist.run.100
         note vmopts
      4. observe timeouts.


      with /net/vmsqe.ru.oracle.com/export/gtee/bin/ute ... -env TONGA_JAR=./tonga-utils-dtonga-hang-fix.jar and export TONGA_DUMP_CORE=true
      taking from http://stt-13.ru.oracle.com/export/home0/projects/Tonga/dist/archive/4.0.1/tonga-utils-dtonga-hang-fix.jar

      So, I hope there is no any deadlocks between FlatProfiler and Compiler and this is just another issue with PlatformEvent::park
