Yes. Both vmstat and iostat do that. I've done again a cvsup today and
there is no changes.
bash# ldd `which iostat`
/usr/sbin/iostat:
libkvm.so.2 => /usr/lib/libkvm.so.2 (0x28052000)
libc.so.3 => /usr/lib/libc.so.3 (0x28057000)
bash# ldd `which vmstat`
/usr/bin/vmstat:
libkvm.so.2 => /usr/lib/libkvm.so.2 (0x28053000)
libc.so.3 => /usr/lib/libc.so.3 (0x28058000)
