Thanks, that's very helpful.  Playing with your code a bit, I narrowed
the problem down to the array.array() structure.  Looking at
help(array), there's a method defined called __deepcopy__, which, it
seems, takes no arguments, while deepcopy is passing it one argument.
Looks like a bug in the array module to me.  Maybe others with more
