Certainly we know from our own testing that making "/bin/ls" an isaexec wrapped program was costly, so we did ship /usr/bin/sparcv9/ls but did not make /bin/ls an isaexec wrapped binary. So the cost can be measured (but shells are bigger and slower to start and the cost of isaexec done in another location might well be negligble) Casper
