Frankly, the version in DCSP is rather slow and unnecessarily limited.  In the future, I hope to address these issues, but I won't be able to do any work until I finish up my current projects.

The Newsqueak papers talk about the implementation of “select”; the Plan 
9 thread(2) or Russ Cox’s libtask have the source code for the “Alt” 
structure and its related code.  It’s a solved problem.
