Specifying a variable for duration and delaying thread startup causes the test to not run

[asfimport]

oliver lloyd (Bug 54480):
Based on the jmx attached:

1. With Delay Thread Startup checked and a variable used for duration - FAILS
2. Without Delay Thread Startup checked and the ${duration} variable used for duration - WORKS
3. With Delay Thread Startup checked but no variable used for duration - WORKS

Created attachment fails.jmx: fails
