Thanks for your work Michael. I've been so grateful to have you and
Chuck and others looking carefully at the code to fix its problems.
In this particular case, I'm not sure I see how (the rest of) your patch
fixes any remaining leak. We do seem to be having a disagreement about
whether or not the reference to typecode can be pre-maturely destroyed,
but this doesn't fit what I usually call a "memory leak." I think
there may be some other cause for remaining leaks.

Good, that is the argument I'm making. Why don't you want to "rely on
Thanks for all your help.
