Well, on the working machine there was a .swank.lisp explicitly setting the communication style to :fd-handler, which I believe is the default; both machines were using :fd-handler.

On SBCL with #+(and SB-THREAD SB-FUTEX) the default is actually :SPAWN.

You're absolutely right. My mistake. Thanks so much for your patience.

So I guess :spawn is somewhat problematic on SBCL. I can live with that, since I think I need :fd-handler anyways for my other software that tries to mess with interrupts.

Cheers,
