I don't know if anyone other than Barry has had a look at the pthreads based hurd that I had in a BitBucket repository, but now that Richard Braun has created a branch on the Savannah servers, I will be removing the BitBucket repo.
The pthreads code is now in rbraun/hurd_with_pthreads. Thank you Mr. Braun for getting this set up, proofing the patch, and removing some of my superfluous and inane comments. Thomas D
