[AGENT++] Thread handle leak (SNMP++ 3.2.21a)

it can be patched immediately ;-)

Just change stop_poll_thread() to;
#ifdef WIN32
    ::WaitForSingleObject(m_hThread, INFINITE);
    CloseHandle(m_hThread);
#elif defined (CPU) && CPU == PPC603

This will be in the next release.

A funny thing: If you don't need the handle after the thread is started,
you can write code like this:
CloseHandle(CreateThread(NULL,0, ThreadA,NULL,0,NULL));
