The following two BQT queries are throwing Blocked Exception. Still reviewing query results but if I find more of these I will
log them to this JIRA.

SELECT stringkey, (SELECT intkey from BQT1.SmallA where Intnum > 22) FROM BQT1.SmallA order by stringkey

SELECT INTKEY, (SELECT TIMESTAMPVALUE FROM BQT1.SMALLA WHERE DOUBLENUM < 25) FROM BQT1.SMALLA ORDER BY Intkey
