Ahhhh... I was wondering about this.  OpenBSD has softupdates as of
2.9, but mentions that one shouldn't use it on sun4c because of
limits to the size of kernel memory or something.  I was recently
looking at NetBSD to try and find a similar warning and didn't see
it, so was rather curious as to why one would have that limit and
not the other...
