+This directory contains test cases that are known to leak references.
+The idea is that you can import these modules while in the interpreter
+and call the leak function repeatedly.  This will only be helpful if
+the interpreter was built in debug mode.  If the total ref count
+doesn't increase, the bug has been fixed and the file should be removed
+from the repository.
+
+Note:  be careful to check for cyclic garbage.  Sometimes it may be helpful
+to define the leak function like:
+
+def leak():
+    def inner_leak():
+        # this is the function that leaks, but also creates cycles
+    inner_leak()
+    gc.collect() ; gc.collect() ; gc.collect()
+
+Here's an example interpreter session for test_gestalt which still leaks:
+
+>>> from test.leakers.test_gestalt import leak
+[24275 refs]
+>>> leak()
+[28936 refs]
+>>> leak()
+[28938 refs]
+>>> leak()
+[28940 refs]
+>>> 
+
+Once the leak is fixed, the test case should be moved into an appropriate
+test (even if it was originally from the test suite).  This ensures the
+regression doesn't happen again.  And if it does, it should be easier
+to track down.
