lesson learned from http://k1024.org/~iusty/blog/entry/perf-null/ – add -DMKSH_SMALL_BUT_FAST which gives more speed (8/20K less cycles, 5/9K less insns, 1.8/2.4k less branches, 65/275 less branch misses) on Debian/amd64 (klibc-static/eglibc) at cost of 0/2 more page faults and 6K/6K more text size
