buffer is not a COM object.  Using Interlocked* functions will not
make it thread safe.  This needs to be put under the dsb lock to be
correct but the odds of a program duplicating a buffer in one thread
while deleting a duplicated buffer in another are slim.  I'll look
into fixing this when I get a chance.
