If wait queues stored lists of waiting processes, then notify could
involve adding run reasons to all waiting processes. Sounds
complicated, but in terms of speed it's probably a lot better than
letting those waiting threads remain active.

It doesn't sound too difficult. Where did you find information on
future versions, though?

Threads for one more compiler (clisp), then distributed programming.
What is process linking?

Do you have any ideas about what the interface should look like for
distributed programming? I've seen some confusing material on erlang
websites which suggested that an erlang programmer could write a
concurrent program without knowing whether it would be run on one
computer (threads) or spread over several. Sounds nice but I never
figured out how that worked.

I tried pulling the latest patch. No problems.
