Ah, ok, sounds possible then. So, the question is whether it would
be preferable to align *all* 32-bit dwords to 4 bytes or just these
which need it. Simplicity/reliability vs. memory usage…

I wonder what the effects would be on typical things, say the libc,
/bin/date, a shell, maybe libperl, and something using TLS.
