ExeMgr memory leak when joining and using limit

[wweeks]

ExeMgr is leaking memory when joining and the query uses a limit clause. Here's an example query that reproduces the problem against the tpch database.

select o_orderkey, o_orderdate, c_acctbal, c_nationkey, o_shippriority,
o_totalprice, o_clerk, c_comment from orders, customer where o_custkey =
c_custkey limit 0,30;

ExeMgr memory usage climbs with each repeated run of the query.

Resolved in 0.9.5.2. The remaining rows are now consumed in the connector connector when a limit clause is used.
