We're seeing the android emulator occasionally hang trying to start up. For example: https://gist.github.com/52b5207b7b1dfe768b0c

where we see:

00:08:08 $ /opt/android/android-sdk-linux/platform-tools/adb -s localhost:33298 logcat -v time
00:08:46 $ /opt/android/android-sdk-linux/platform-tools/adb connect localhost:33298
00:08:46 [android] Attempting to unlock emulator screen
00:08:46 $ /opt/android/android-sdk-linux/platform-tools/adb -s localhost:33298 shell input keyevent 82
08:05:15 Build timed out due to Global Timeout (after 480 minutes). Marking the build as aborted.

Can the plugin attempt to send these keys again after some timeout?
