title: Android cpuacct.usage file
body: <p>I found, in the emulator, under directory /acct/uid/10041 a file called cpuacct.usage and cpuacct.usage_percpu.
  Cat on the file gave me this: <em>839133794</em></p>
  
  <p>Can some one tell me how and for what is this file used? Is it a way to limit the CPU usage for a given uid?</p>
  
  <p>Thanks,
  Romain</p>
