Mark Addleman commented on TEIID-2676:
--------------------------------------

I get a barrage of "Row received" with no delay.  I'm running an JDK "1.7.0_11-b21" on an 8 core laptop.  Other observations:  
I tend to see this kind of behavior more with stored procedures than with tables, although with uploaded test case, I get the same behavior with both table and stored procedure.
I don't have time to come with a test case now but it seems the misbehavior is also tied to the complexity of the query - adding a join can trigger the bug regardless of the forkable setting.

> It appears that when isForkable=false, the delay specified in DataNotFoundException is not honored.  I have seen similar behavior even when isForkable=true but it's a Heisenbug:  when I add logging, it goes away.  It smells like a race condition.
