title: easy way to parse a text file?
body: <p>I'm making a load balancer (a very simple one). It looks at how long the user has been idle, and the load on the system to determine if a process can run, and it goes through processes in a round-robin fashion.</p>
  
  <p>All of the data needed to control the processes are stored in a text file. 
  The file might look like this:</p>
  
  <pre><code> PID=4390 IDLE=0.000000 BUSY=2.000000 USER=2.000000
   PID=4397 IDLE=3.000000 BUSY=1.500000 USER=4.000000
   PID=4405 IDLE=0.000000 BUSY=2.000000 USER=2.000000
   PID=4412 IDLE=0.000000 BUSY=2.000000 USER=2.000000
   PID=4420 IDLE=3.000000 BUSY=1.500000 USER=4.000000
  </code></pre>
  
  <p>This is a university assignment, however parsing the text file isn't supposed to be a big part of it, which means I can use whatever way is the quickest for me to implement. </p>
  
  <p>Entries in this file will be added and removed as processes finish or are added under control.</p>
  
  <p>Any ideas on how to parse this? </p>
  
  <p>Thanks.</p>
