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.
