+1 for not using tasklets. At least in Android the real-time thread
scheduling latency is important. Tasklets are not visible to the
scheduler and hence cause latency spikes for real-time threads. These
latency spikes can be observed by users, e.g. if the real-time thread is
involved in audio playback.
