The issue was briefly discussed, there were problems with MS-Windows that I do not follow and cannot easily test, Dmitry played it safe and left MS-Windows alone, and I followed his lead. It was reasonable for us to be cautious about enabling USE_STACK_LISP_OBJECTS on an untested and potentially-problematic platform. And it was reasonable for you to enable USE_STACK_LISP_OBJECTS on MS-Windows once you installed further changes to fix the problems and had tested the result. There was nothing sneaky about any of this, and the above-quoted remarks are unwarranted. By the way, I share Stefan's concern that the performance improvements of USE_STACK_LISP_OBJECTS haven't been adequately demonstrated.
