      Description


      On jtg-linux3, Volanomark crashed after 28 hours.

      This looks like a race between jvmstat and VM shutdown code.
      In particular, PeriodicTask::deroll() does not use a lock, it is
      possible that the watcher thread is processing a StatSampler task while
      the StatSampler::disengage() call from the main thread pulls the bug
      out from under it.

      To reproduce the bug
      1. telnte jtg-linux3
      2. export JAVA_HOME
      3. /net/jtgb4u4c.sfbay/export/sail8/bigapps/tests/runvmark.ksh -server
      4. log files are under /bt/VolanoMark*
      check if run.vmark.out is up-to-date. If not, volanomark hungs.

      THe libjvm.so is attached.
