Hi, lparallel tests now pass with the timeout change in this pull request


One thing that puzzles me -- I checked old versions of ABCL back to
1.0.0, and none gave an indefinite wait for (sleep 0). Do you remember
why you changed (sleep 0) to (sleep 0.01) in thread-yield in February
2011? I changed it back to (sleep 0) in the pull request, but I didn't
realize I was undoing your change until this moment.
