I think it's probably more about turning off malloc debugging and using
a non-debug kernel. To turn off malloc debugging, create a symlink
/etc/malloc.conf -> aj. It's a broken link of course, but it works -
see malloc(3) for more information. To turn off debugging in the
kernel, comment-out any WITNESS, INVARIANTS etc options in the config -
most are within a clearly defined block ("# Debugging for use in
-current"), but there's also 'makeoptions DEBUG=-g' at the top
which should probably be turned off, too.
