Description
Termination times some times are unbalanced as in an example from running
GCOld.

     [Termination (ms):  2.0  2.0  2.0  2.0  2.0  2.0  2.0  12.9  2.0  0.0  2.0  2.0  2.0  12.9  12.9  12.9 

This may indicate that some threads are not getting GC work to do.

EVALUATION

We will improve the logging and decrease the likelyhood of getting to the sleep(1) call in offer_termination().
