 Try to determine whether the loop iterations are independent.  In that case, they can all be executed by one thread.
 
-Otherwise, iterations must be distributed among the threads in some nondeterministic way.  This could blow up rapidly!
+Otherwise, iterations must be distributed among the threads in some nondeterministic way.  This could blow up rapidly!  Also, a thread does not have to execute its iterations in increasing order.  It can execute them in any order.
+
+Trying a few different things for now: picking a particular scheduling policy like round-robin (status with chunk size 1).  Of course you can always do this if schedule is specified to be static.
+
+The question is do we ever want to try to explore these interleavings?
+
+Is there any loss of generality  by just running all iterations concurrently?
+
+=== `sections` ===
+
+If there are n sections, create n functions: section1, section2, ....  Again the question is how to distribute them among threads and in what order.
+As with loops, you really want to check these are independent and only do the interleaving exploration as a last resort.
