tv a7d1d15c39 KMEMSTATS is documented in options(4) as being a possible severe 
performance hit, and on an 80386 processor, it most certainly is.  Pull it
from the GENERIC (and DISKLESS "generic") kernels--configure it in
yourself if you actually need it.

# DISKLESS -- Generic machine setup for diskless boot.
# This kernel can be loaded from a bootable floppy (i.e. kernel-copy)
# and will use NFS for root and swap. (No local disk space needed.)
