-script: test_leak.py
-
-This script attempts to repeatedly insert the same list of rows into
-the database table, causing a duplicate key error to occur. It will
-then roll back the transaction and try again.
-
-Database table schema:
-    -- CREATE TABLE t (foo TEXT PRIMARY KEY);
-
-There are two ways to run the script, which will launch one of the
-two functions:
-
-# leak() will cause increasingly more RAM to be used by the script.
-$ python <script_nam> leak
-
-# noleak() does not have the RAM usage problem. The only difference
-# between it and leak() is that 'rows' is created once, before the loop.
-$ python <script_name> noleak
-
-Use Control-C to quit the script.
