* Include this file once in each DLL that relies on SystemInfo.h:
* threadSafeShutdown(). Note that Thread.cpp has a more elaborate
* DllMain, that also provides this functionality separately.
*
* Teardown is in the reverse order of the DLL dependencies used
* during the load phase. The calls to DllMain and the static
* destructors are from the same thread, so no locking is necessary
* and there is no downside to an invocation of DllMain by multiple
* Qpid DLLs.
