Limiting Total # of TaskTracker threads

[Jimmy Wan]

The properties mentioned here: http://wiki.apache.org/hadoop/FAQ#13
have been deprecated in favor of two separate properties:
mapred.tasktracker.map.tasks.maximum
mapred.tasktracker.reduce.tasks.maximum

I'd like to limit the total # of threads on a task tracker (think limited  
resources on a given compute node) to a given number, and there does not  
appear to be a way to do that anymore. Am I correct in my understanding  
that there is no capability to do this?
