Well, hop into Macsbug and do a heap dump (hd).  If every single block is
long aligned, then I'd say the odds are really good that you've found out
for sure.  Either that, or you should call Ripley's because the odds against
all allocations "accidentally" being long aligned are about a grillion to one.
