* The fasl loader has reduced the startup mmap frenzy for code
...
objects from 5242 pages (almost one page per code object) down
to 785 pages. Special thanks to Michael Adams for counting the
the number of pages that were used and touched at startup; without
his help, I wouldn't have optimized it in about 10 minutes of
coding time.
