title: logcat filtering and number of lines
body: <p>This issue has been puzzeling me and I hope to find an answer from you.</p>
  
  <p>I am trying to display the last 100 occurances(or lines) of logs that have my class xx tag and of level Info</p>
  
  <p>this is done using</p>
  
  <p>Adb logcat -t 100 -v long xx:I *:s </p>
  
  <p>I am getting only last 12 or so occurances of xx:I not 100.</p>
  
  <p>could it be that logcat is readig last 100 lines of logs and filtering them based on my criteria? Shouldnt it display last 100 tagged lines? </p>
