Set (and :sb-thread :sb-safepoint :sb-thruption :sb-wtimer) + to test these experimental features. Known remaining bugs include minor + thread safety issues, less timely freeing of memory by GC, and certain + (not yet optimally low) runtime overhead. Thanks to Anton Kovalenko. * optimization: CL:SORT and CL:STABLE-SORT of lists are faster and use fewer comparisons, particularly on almost-sorted inputs. * bug fix: Reading floats with large exponents no longer takes too much time -- 1.7.10.4
