The OPEN-BLOCK-OPTIMIZATIONS declaration no longer exists.

Sorry, the URL above should have been <http://mumble.net/~campbell/scheme/mit-skip-list.scm>, which has the necessary procedure integration declarations for the bug to be exhibited. To test the bug with that file, simply change the NO-OPEN-BLOCK-OPTIMIZATIONS declaration to an OPEN-BLOCK-OPTIMIZATIONS declaration.

The OPEN-BLOCK-OPTIMIZATIONS declaration inhibits procedure integration in certain cases. I haven't been able to isolate exactly where the problem arises, but if code like wttree.scm in the runtime or <http://mumble.net/~campbell/scheme/skip-list.scm> is SF'd with OPEN-BLOCK-OPTIMIZATIONS declared, KEY<? is not integrated in the body of MAKE-WT-TREE-TYPE and MAKE-SKIP-LIST-TYPE, which dramatically impacts performance.
