I'm glad it leaked: %p abuse is unfortunately not that rare, and getting
developers' attention is a good thing.  E.g., every time I do kldstat(8)
on my PowerPC box I sigh:

% kldstat
Id Refs Address    Size     Name
 1    7 0x100000 e0c378   kernel
 2    1 0xd20dd000 1d000    tmpfs.ko
 3    2 0xd2114000 18000    geom_sched.ko
 4    1 0xd2131000 13000    gsched_rr.ko
