Linux doesn't allow any writes to shared libraries or executables that are currently running: ulysses:/bin# LC_ALL=C /bin/sh -c "cat > /bin/bash" /bin/sh: /bin/bash: Text file busy For shared libraries, we use MAP_COPY. Maybe we can use this for executables, too? This opinion might be ignorant of any hair that is involved with exec ;) Thanks, Marcus -- `Rhubarb is no Egyptian god.'
