+fail
+====
+
+run a program until it fails and gather statistics
+
+Elaborations from a favorite bash one-liner::
+
+    I=0; while ./do_some_things.py --param $arg; do I=$((I+1)); echo Iteration ${I}; sleep 1; done
+
+fun things to try
+----------------
+
+Russian roulette (with two chambers)::
+
+    fail 'exit $(expr $RANDOM % 2)'
