Thanks for the info.  Weird coincidences - it seems Doug Santry wrote
that paper while at UBC - which is the university I'm currently
physically closest to - and it was co-authoured by Norman Hutchinson -
who also worked on Emerald - which was just a day or two ago mentioned
on the Erlang mailing list - and Emerald had as one of its primary
features, migration of objects (/processes) from processor to processor
- which is also one of the things I understand Matt has been planning
for DragonFlyBSD...
