Yep. But that wouldn't help in this case, although my description was 
too spotty. The general structure here is

while (true) {
    wait_for_something_to_happen_with_timeout
    if (something_happened) {
        process
    }
    if (userCancelled) {
        do_a_clean_exit
    }
}

Most of the time is spent waiting.

I just want to read SMS messages stored in a mobile phone. For some 
reason, transmitting them takes some time. It produces a noticable 
delay to get my meager 15 messages. During this time the UI just 
doesn't look and behave nice.
