What could one anticipate to be the symptoms of such a missing
lockless_dereference()?

The Alpha kernel is behaving pretty well provided one builds a machine
specific kernel and UP.  When running an SMP kernel some packages
(most notably the java runtime, but there are a few others) occasionally
lock up in a pthread call --- could be a problem in libc rather then the
kernel.

There are a few of us still running recent kernels on Alpha.  I am
maintaining the unofficial Debian alpha port at debian-ports, and the
Debian popcon shows about 10 installations of Debian Alpha.

Cheers
