Or use an nscd like Solaris?

I'm more worried about the performance hit than foot-shooting (schg is
protection enough I think, and I like beagles).

I believe dynamically-linked programs still are ~20% slower than static
ones, and for small programs like sed, awk, expr, sh, basename, tr, and
the like, the larger (constant) startup time becomes significant also.

Anyone want to benchmark a medium-sized portbuild with static vs
dynamic /bin and /sbin?
