If it's possible given the time constraints and cvs tagging activity, I'd be happy if the preferred-communication-style checked only :sb-thread, and if the slime release notes for 1.2 required an sbcl of 0.8.21 or later.
Does :sb-thread reasonably imply a working threads implementation? My only concern is that if SBCL on some platforms would have :sb-thread by default but not a reliable implementation, i.e. if SLIME suddenly starts using threads by default on platforms where it shouldn't.
I think (Dan reads this list, so he'll correct me if I'm wrong) that from 0.8.21 :sb-thread implies the previous combination of :sb-thread and :sb-futex before. That said, there is a possible snafu where an sbcl with :sb-thread will nevertheless refuse to start new threads if the underlying kernel is insufficiently futexed.
Doesn't that include, for example 2.4 kernels? Would this change imply that anyone grabbing a 0.8.21 SBCL and SLIME 1.2 on a 2.4 kernel would lose by default since SBCL would refuse to start new threads?
