I think all the user land debugging is turned off, though I'm not
sure. Is there anything else one needs to do to ensure optimal
performance (e.g. no debugging is enabled, etc) besides the following?

1. remove WITNESS/INVARIANTS/etc from the kernel
2. add WITHOUT_LIBKSE=yes to /etc/make.conf prior to building world
3. Ensure MALLOC_PRODUCTION is set in
/usr/src/lib/libc/stdlib/malloc.c (default in RELENG_7, right?)

Thanks,
Josh
