Comment (by Joel Sherrill):

 The goal was to ensure generically that the start of a partition was
 aligned the same on all architectures. Buffers allocated from one should
 meet the alignment requirements of a malloc'ed object which means the
 alignment of a double. It is the user's responsibility that the memory
 passed in is aligned properly. I contend that this test is defective if it
 does not address alignment.
