+%% Test for Issue 20, courtesy Bart van Deenen, 1 Feb 2012.
+%% The bug was a missing check of what pool a queued execution was waiting for.
+%% The fix included introducing wait queues per pool.
+%% To run this test, make a folder test, move this file into it,
+%% move emysql into test/emysql, clone eunit into test/eunit:
+%% $ git clone https://github.com/abhay/eunit.git # then do
+%% $ cd emysql && make && cd .. && cd eunit && make && cd ..
+%% $ erlc issue20.erl && erl -pa emysql/ebin -s issue20 test -s init stop -noshell
+%% /hd 2 1 12
