Testers please

[Martien Friedeman]

Thanks for that for that Scott.
Most of hassle is storing the program flow.

For example:
Iteration 3 of the loop starting on line 12 has itself a loop on line 15
that has 14 iterations. 
Iteration 4 of the loop starting on line 12 has a completely different set
of iterations for the loop on line 15. If at all(!)

All that is stored in a tree which I pickle and write to the database.

Massive program runs will create large trees.
And this pickling is expensive.
