I know of one large, hard-crunching compiler [name deleted to protect the guilty] which put out a NUL to the terminal each time it read a line of source, to keep its priority nice and high. Argh. I'm not saying it can't be done well, just that care is needed. Terminal input should be considered much more significant than output, for purposes of scheduling. -- Henry Spencer @ U of Toronto Zoology {allegra,ihnp4,linus,decvax}!utzoo!henry
