Alphas cope with this quite well, although you will see "unaligned trap"
messages in the "messages" log. Apparently the processor takes care of the unaligned
access internally at the cost of some speed.

Exim runs well under Alpha Linux.
I'd wonder whether the signal 11s and memory violations are more related to
a hardware problem.
