Thanks!

The way things are set up now I think you never go through
PLy_input_tuple_funcs twice, unless the cache is determined to be
invalid and then you recreate the function from scratch.

But of course it's better to be safe than sorry and even if I'm right
and it was never executed twice, any refactoring effort might have
broken it easily.
