I was going to make the suggestion that malloc et al. could be replaced with
palloc etc but then that raises too many complications without just shooving
everything into a long lived context anyway. Also I think we've got to rely on,
i.e. it is sensible to do so, the underlying language handling memory
correctly.

Hmmm...there do seem to be a few mallocs in plpython.c . I haven't looked very
closely but nothing jumped out at me as being obviously wrong from the grep
output.
