Linuxcatches SIGBUSes and emulates theisunaligned memory access in
software.  This is very, very slow and when I first tested gpg on a
the fasted Alpha available at that time, I was wondering why it was
so slow - until the susadmin asked whether I still need the logfiles
with all the entries "unaligned memory access - emulated" :-)

There used to be a syscall which disables this emulation and gives
you a SIGBUS.
