      Description

      We recommend 64-byte padding in memory allocations, but in practice some systems may emit buffers that are only 8-byte aligned. We should take a look through the format documents and perhaps indicate that 64-byte padding is the preferred padding but that 8-byte padding is the required padding.

      In particular, it should be clear that each buffer in an IPC payload must start on an aligned 8-byte offset, but it does not necessarily need to be 64-byte aligned.
