Treat a 'current' value of 0 as unlimited as a failsfe. When limiting I/O, a value of 0 makes no sense as a limit. No progress can be made. Trade the possibility that someone might be doing something clever to achieve ultra-low I/O limits vs the damage of not ever making progress on an I/O in favor of making progress. Now the machine won't be useless if this accidentally gets requested. Sponsored by: Netflix
