Problem with StatelessConnectionPool and Threads on Windows XP

Question

I am trying to use a StatelessConnectionPool in a multithreaded app under Windows using 10g. The problem is that when my application is exiting and I go to terminate the StatelessConnectionPool, I get an access violation inside Environment::terminateStatlessConnectionPool.
A short program that demonstrates the problem is at the end of this post. One thing I have noticed is that by calling terminateConnection inside the thread instead of releaseConnection the problem goes away. However, performance really degrades. Thanks in advance.

StatelessConnectionPool* connPool = NULL;
//Derived from opur Thread class
class TestThread : public Thread

     TestThread(void){}

     //get an object 10 times, sleeping every 500 msecs in between
     virtual DWORD run(void)
          printf("Thread 0x%08x Enter...\n", GetCurrentThreadId());
          Sleep(500);
          int i = 0;
          while(i < 10)
               try
                    Connection* conn = connPool->getConnection();
                    Statement* stmt = conn->createStatement("select Ref(c) from consumers c where pid = 7038878582");
                    ResultSet* rs = stmt->executeQuery();
                    if(rs->next())
                         Ref<Consumers> consumer = rs->getRef(1);
                         printf("Thread 0x%08x #%d - %.0f\n", GetCurrentThreadId(), i+1, (double)consumer->getconsumerid());
                    stmt->closeResultSet(rs);
                    conn->terminateStatement(stmt);
                    connPool->releaseConnection(conn);
                    //connPool->terminateConnection(conn);
                    Sleep(500);

               thread->start();
               handles[i] = thread->getThreadHandle();
          WaitForMultipleObjects(numThreads, handles, TRUE, INFINITE);
          //Clean up
          terminateConnection();

When I search MetaLink for bug 4183098, it says there's nobug 4183098. Any information on this?
