With a bit of work, very complex applications can be written using a super-loop, without making the application impossible to maintain. The hard part - but it is always hard - is to prove a worst-case response time for any combination if timeouts and input stimuli.
well Per, I guess a 'superloop' is the same as a 'workloop'.

you can prioritize the operation:

for (;;)
{
if (MostImportantJob) continue;
...
if (NextToLeastImportantJob) continue;
LeastImportantJob();
}

\
yes, this takes thought.
