ulatencyd binary package in Ubuntu Precise armel

 Ulatency is a daemon that controls how the Linux kernel will spend it's
 resources on the running processes. It uses dynamic cgroups to give the
 kernel hints and limitations on processes.
 .
 It strongly supports the lua scripting language for writing rules and the
 scheduler code.
 .
 The Linux scheduler does a pretty good job to give the available resources
 to all processes, but this may not be the best user experience in the
 desktop case. ulatencyd monitors the system and categorizes the running
 processes into cgroups. Processes that run wild to slow down the system
 by causing massive swaping will be isolated.
