trq-2013 MOM was dropping the ball becauase it got  an error 4 (Interrupted system call) and was not retrying it. So, I put in some retry logic.
Added unit test for trq-2013 and found a bug in the process. Also fixed a broken unit test.
Merge branch '4.2-dev' of https://github.com/adaptivecomputing/torque into 4.2-dev
