Yes. As a practical matter though, until an @Contended attribute
or something like it is supported across JVMS (see list archives for
discussion), you cannot arrange reliable two-sided padding
for objects with mixed field types (ints, longs, refs that may be
either 32 or 64 bits, etc), so one-sided is the best you can do.
