Title:
  android-input logs are not flushed as soon as they happen

Status in Mir:
  Fix Committed
Status in mir package in Ubuntu:
  New

Bug description:
  steps:

  1- enable android-input logging
  eg, by adding "export MIR_SERVER_LEGACY_INPUT_REPORT=log;export ANDROID_LOG_TAGS=*:v" to /usr/share/ubuntu-touch-session/usc-wrapper

  2- $ sudo tail -f /var/log/lightdm/unity-system-compositor.log

  
  3- touch the screen

  
  expected outcome:
  you see the log lines appearing for the touch events as they happen

  actual outcome:
  the log file is written after every N bytes of android-input logging take place. So the update happens in chunks and sometimes it stops in the middle of a log entry.
