Hi Nikolaus, I've been trying to get SBCL to pass all the thread tests. I've got two patches locally on my system that get it further along (one is a really nasty issue related to a bug in the nanosleep system call on 64bit X86). The bug that Nikodemus points out below is the other patch I have on my local system. Right now OS X is still not passing all the tests. The latest hang up is the internal use of Lutexes for OS X don't support deadlines and this causes the current set of tests (with the 2 local patches I have applied so that the tests get to this point) to hang. Another person on this list (David Rager) also has some local code that he sent me that I'm going to try out. I primarily use OS X so I'm motivated to solve these remaining problems :-) Thanks, Glenn V.
