Hello.
In the scope of this project https://github.com/cl-test-grid/cl-test-grid I and Robert Goldman run tests of CL libraries on various CL implementations.
Bordeaux threads tests fails on some implementations, sometimes due to buts in the tests I suppose.
You may find reports here http://common-lisp.net/project/cl-test-grid/
Probably the most convenient report to overview a single library status is this one: http://common-lisp.net/project/cl-test-grid/pivot_lib-lisp_ql.html
Between the test results for the recent version of quicklisp and the previous one, bordeaux-threads has only one regression: sbcl-1.0.54.45-a2bef14-macosx-x64.
Probably it's due to some bug (like race conditions) in the tests, because the Qicklisp Blog doesn't list bordeaux-threads between updated projects in the last distro update, and if it's true, than the results are from the same bordeaux-threads version. http://blog.quicklisp.org/2012/02/february-dist-update-now-available.html
