I tried to locate which program was flipping ECHO etc during the boot but 
eventually gave up. Trying to flock the tty didn't help either. Looks like 
TIOCSLCKTRMIOS is the most sensible. Attached is a patch, which does this.

It quits if it cannot read/write the locks which might be unnecessary but hard 
to see when that would happen.
