+
+I wrote these unittests to investigate some odd transaction
+behavior when doing unittests of integrating non sub transaction
+aware objects, and to insure proper txn behavior. these
+tests test the transaction system independent of the rest of the
+zodb.
+
+you can see the method calls to a jar by passing the
+keyword arg tracing to the modify method of a dataobject.
+the value of the arg is a prefix used for tracing print calls
+to that objects jar.
+
+the number of times a jar method was called can be inspected
+by looking at an attribute of the jar that is the method
+name prefixed with a c (count/check).
+
+i've included some tracing examples for tests that i thought
+were illuminating as doc strings below.
+
+TODO
+
+    add in tests for objects which are modified multiple times,
+    for example an object that gets modified in multiple sub txns.
