*Sigh*. As a hack, I've been relying on the process registry for
something -- luckily in a way that's not going to mean ongoing
performance bottlenecks if I serialize the name registrations, since the
registrations are restricted to a brief initialization phase. However,
the realization that I was using well-known race-condition code sent me
on a literature search that serendipitously turned up this:
"Fallacies of Distributed Computing Explained"
To the extent that the course is about *distributed* computing, not just
concurrent computing, structuring the discussion around the now-classic
Eight Fallacies could be useful.
