	I was talking this over with someone the other day who claimed
that SunOs' more recent versions have "often used" utilities like /bin/ls
statically linked because there were complaints of performance hits -
can anyone confirm or deny this? I haven't has access to a machine
running a SunOS more recent than 4.0. [I realize that "often used" and
critical utilities might be statically linked to prevent the whole
system being rendered useless by a hit on the library. Is "ldconfig"
or whatever it's called still a dynamically linked file?]
