title: adb reboot doesn't complete
body: <p>I'm trying to run a few test packages on my device through a shell script which runs every night and for that I need to run the adb reboot command. My problem is that the 'adb reboot' command does make the system reboot, but it never completes (I need to do a keyboard interrupt if I run it manually in order to issue another command) I was wondering if there is anyway I could make my script go to the next command after a certain fixed amount of time? What could be going wrong with the adb reboot command? Sorry if my question is vague.</p>
  
  <p>Thanks.</p>
