Android is based on Linux, so most of the files were identical sans some subtle discrepancies caused by drift over time. This discrepancies were making code base harder to maintain and in fact were hiding bugs. For example, on Android eventhandler's implementation of timers which relied on passing timeout to `epoll_wait` contained a bug which was not present on Linux which used `timerfd` instead.
