Thanks Christoph! I had not realised the consequences of the adaptive
error_bound in the first pass. Quite simply I thought it would - at the same
time - speed up calculations and increase accuracy! Well well well... Things
are never as simple as one believes...

Yes, the recursion_limit is an issue I have been thinking about. I had
already tried as a test a value of 1 but that was ugly.
Thanks for your comments. Much appreciated!
