Description:
Certain statements (the currently only known example: a simple select) prevents
errors in later statements from being return, causing the client to hang.

How to repeat:
create table t1 ( x int );

delimiter //
create procedure p1()
begin
  declare c cursor for select x from t1;
  close c;
end//
create procedure p2()
begin
  declare c cursor for select x from t1;
  select 'Boo';
  close c;
end//
delimiter ;

-- this returns the expected error
call p1();
-- this will hang
call p2();
