The attached patch makes the repro run without getting an OutOfMemory error.
This is achieved by removing the LOB object from the locator mapping.

I am not setting patch available since test cases should also be added,
and I have not run the regression test suites.

> Retrieving from a large table with lobs gives an OutOfMemoryException, even if free() is explictly called on the lob.   I believe this is because EmbedConnection.addLobMapping is called for every lob creation but is never cleared until commit or rollback, even if the lob is freed.
