Of course, now that I think about it, aligning it probably works
mostly because the size is almost exactly one cache line.  If it were
any bigger or smaller, aligning it more wouldn't help.  So maybe we
should also do something like what LWLocks do, and make a union
between the actual structure and an appropriate array of padding bytes
- say either 64 or 128 of them.
