[drlvm] hythread_suspend_all hangs sometimes
--------------------------------------------

                 Key: HARMONY-5870
                 URL: https://issues.apache.org/jira/browse/HARMONY-5870
             Project: Harmony
          Issue Type: Bug
          Components: DRLVM
    Affects Versions: 5.0M7
         Environment: WinXP PentiumM (T42p laptop)
            Reporter: Alexey Varlamov
         Attachments: ConcurrentExceptionTest.java

I've tried ConcurrentExceptionTest from http://www.javaspecialists.eu/archive/Issue162.html and it hangs (and keeps CPU 100% busy) each ~3rd run on my  laptop. I could not reproduce it on server machines though.

Backtrace of the busy thread is always this:
